Abstract

The compositional graded quaternary barriers (GQBs) instead of ternary/conventional quantum barriers (QBs) have been used to numerically enhance the efficiency of AlGaN-based ultraviolet light-emitting diode (LED). The performance of LED with GQBs is examined through carrier concentrations, energy band diagrams, radiative recombination, electron and hole flux, internal quantum efficiency (IQE), and emission spectrum. As a function of the operating current density, a considerable reduction in efficiency droop is observed in the device with composition-graded quaternary barriers as compared to the conventional structure. The efficiency droop in case of a conventional LED is ~77% which decreased to ~33% in case of the proposed structure. Moreover, the concentration of electrons and holes across the active region in case of the proposed structure is increased to ~156% and ~44%, respectively.

Abstract

Universal filtered multi-carrier (UFMC) is being studied as the favourable waveforms supporting the visible light communication broadcasting systems. However, the UFMC system faces a serious performance degradation on the transmitter side due to its high peak-to-average power ratio (PAPR). High PAPR of the signal is an analytical intention parameter for mobile networks, and it is necessary to minimize it as much as possible. This paper focuses on the PAPR reduction of the UFMC scheme. An efficient hybrid method of the PAPR reduction has been proposed and analysed through the Matlab™ simulation. The proposed hybrid scheme consists of a mixture of the selected-mapping method and the discrete Hartley transform precoding for a UFMC system (SLM-DHT-P-UFMC). The simulation results show that the proposed hybrid system has a better PAPR reduction performance compared to traditional SLM-UFMC and DHT-P-UFMC systems. Hence, SLM-DHT-P-UFMC is considered to be the suggested scheme in visible light communication broadcasting systems.

Abstract

Accurate determination of material parameters, such as carrier lifetimes and defect activation energy, is a significant problem in the technology of infrared detectors. Among many different techniques, using the time resolved photoluminescence spectroscopy allows to determine the narrow energy gap materials, as well as their time dynamics. In this technique, it is possible to observe time dynamics of all processes in the measured sample as in a streak camera. In this article, the signal processing for the above technique for Hg(1-x)CdxTe with a composition x of about 0.3 which plays an extremely important role in the mid-infrared is presented. Machine learning algorithms based on the independent components analysis were used to determine components of the analyzed data series. Two different filtering techniques were investigated. In the article, it is shown how to reduce noise using the independent components analysis and what are the advantages, as well as disadvantages, of selected methods of the independent components analysis filtering. The proposed method might allow to distinguish, based on the analysis of photoluminescence spectra, the location of typical defect levels in HgCdTe described in the literature.

Abstract

In this study, solar cells based on copper oxide and titanium dioxide were successfully manufactured using the reactive direct-current magnetron sputtering (DC-MS) technique with similar process parameters. TiO2/CuO, TiO2/Cu2O/CuO/Cu2O, and TiO2/Cu2O solar cells were manufactured via this process. Values of efficiencies, short-circuit current, short-circuit current density, open-circuit voltage, and maximum power of PV devices were investigated in the range of 0.02÷0.9%, 75÷350 µA, 75÷350 µA/cm2, 16÷550 mV, and 0.6÷27 µW, respectively. The authors compare solar cells reaching the best and the worst conversion efficiency results. Thus, only the two selected solar cells were fully characterized using I-V characteristics, scanning electron microscopy, X-ray diffraction, ellipsometry, Hall effect measurements, and quantum efficiency. The best conversion efficiency of a solar cell presented in this work is about three times higher in comparison with the authors’ previous PV devices.

Additional info

Opto-Electronics Review was established in 1992 for the publication of scientific papers concerning optoelectronics and photonics materials, system and signal processing. This journal covers the whole field of theory, experimental verification, techniques and instrumentation and brings together, within one journal, contributions from a wide range of disciplines. Papers covering novel topics extending the frontiers in optoelectronics and photonics are very encouraged. The main goal of this magazine is promotion of papers presented by European scientific teams, especially those submitted by important team from Central and Eastern Europe. However, contributions from other parts of the world are by no means excluded.

Articles are published in OPELRE in the following categories:

-invited reviews presenting the current state of the knowledge,

-specialized topics at the forefront of optoelectronics and photonics and their applications,

-refereed research contributions reporting on original scientific or technological achievements,

-conference papers printed in normal issues as invited or contributed papers.

Authors of review papers are encouraged to write articles of relevance to a wide readership including both those established in this field of research and non-specialists working in related areas. Papers considered as “letters” are not published in OPELRE.

Opto-Electronics Review is published quarterly as a journal of the Association of Polish Electrical Engineers (SEP) and Polish Academy of Sciences (PAS) in cooperation with the Military University of Technology and under the auspices of the Polish Optoelectronics Committee of SEP.

Policies and ethics:

The editors of the journal place particular emphasis on compliance with the following principles:

Ethical policy of Opto-Electronics Review

The ethical policy of Opto-Electronics Review follows the European Code of Conduct for Research Integrity and is also guided by the core practices and policies outlined by the Committee on Publication Ethics (COPE).

Authors must be honest in presenting their results and conclusions of their research. Research misconduct is harmful for knowledge.

Research results

Fabrication, falsification, or selective reporting of data with the intent to mislead or deceive is unethical, as is the theft of data or research results from others. The results of research should be recorded and maintained to allow for analysis and review. Following publication, the data should be retained for a reasonable period and made available upon request. Exceptions may be appropriate in certain circumstances to preserve privacy, to assure patent protection, or for similar reasons.

Authorship

All those who have made a significant contribution should be given chance to be cited as authors. Other individuals who have contributed to the work should be acknowledged. Articles should include a full list of the current institutional affiliations of all authors, both academic and corporate.

Competing interests

All authors, referees and editors must declare any conflicting or competing interests relating to a given article. Competing interests through their potential influence on behavior or content or perception may undermine the objectivity, integrity, or perceived value of publication.

Peer Review

We are committed to prompt evaluation and publication of fully accepted papers in Opto-Electronics Review’s publications. To maintain a high-quality publication, all submissions undergo a rigorous review process.

Characteristics of the peer review process are as follows:

• Simultaneous submissions of the same manuscript to different journals will not be tolerated.

• Manuscripts with contents outside the scope will not be considered for review.

• Opto-Electronics Review is a single-blind review journal.

• Papers will be refereed by at least 2 experts as suggested by the editorial board.

• In addition, Editors will have the option of seeking additional reviews when needed. Authors will be informed when Editors decide further review is required.

• All publication decisions are made by the journal’s Editor-in-Chief based on the referees’ reports. Authors of papers that are not accepted are notified promptly.

• All submitted manuscripts are treated as confidential documents. We expect reviewers to treat manuscripts as confidential material.

• Editors and reviewers involved in the review process should disclose conflicts of interest resulting from direct competitive, collaborative, or other relationships with any of the authors, and remove oneself from cases in which such conflicts preclude an objective evaluation. Privileged information or ideas that are obtained through peer review must not be used for competitive gain.

• A reviewer should be alert to potential ethical issues in the paper and should bring these to the attention of the editor, including any substantial similarity or overlap between the manuscript under consideration and any other published paper of which the reviewer has personal knowledge. Any statement, observation, derivation, or argument that had been previously reported should be accompanied by the relevant citation.

• Personal criticism is inappropriate.

Plagiarism

Reproducing text from other papers without properly crediting the source (plagiarism) or producing many papers with almost the same content by the same authors (self-plagiarism) is not acceptable. Submitting the same results to more than one journal concurrently is unethical. Exceptions are the review articles. Authors may not present results obtained by others as if they were their own. Authors should acknowledge the work of others used in their research and cite publications that have influenced the direction and course of their study.

Plagiarism is not tolerated. All manuscripts submitted to Opto-Electronics Review will be checked for plagiarism (copying text or results from other sources) and self-plagiarism (duplicating substantial parts of authors’ own published work without giving the appropriate references) using the CrossCheck database (iThenticate plagiarism checker).

Duplicate submission

Simultaneous submissions of the same manuscript to different journals will not be tolerated. The submitted article will be removed without consideration.

Corrections and retractions

All authors have an obligation to inform and cooperate with journal editors to provide prompt retractions or correction of errors in published works.

• The journal will issue retractions if:

• There is clear evidence that the findings are unreliable, either as a result of misconduct (e.g., data fabrication or honest error - miscalculation or experimental error);

• The findings have previously been published elsewhere without proper cross-referencing, permission or justification (i.e., cases of redundant publication);

• It constitutes plagiarism;

• It reports unethical research.

• The journal will issue errata, if:

• A small portion of an otherwise reliable publication proves to be misleading (especially because of honest error);

• The author list is incorrect.

Other forms of misconduct include failure to meet clear ethical and legal requirements such as misrepresentation of interests, breach of confidentiality, lack of informed consent and abuse of research subjects or materials. Misconduct also includes improper dealing with infringements, such as attempts to cover up misconduct and reprisals on whistleblowers.

The primary responsibility for handling research misconduct is in the hands of those who employ the researchers. If a possible misconduct is brought to our attention, we will seek advice from the referees and the Editorial Board. If there is the evidence, we will resolve the matter by appropriate corrections in the printed and online journal; by refusing to consider an author's future work and by contacting affected authors and editors of other journals.

Human and Animal Rights

If the work involves the use of human subjects, the author should ensure that the work described has been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans; Uniform Requirements for manuscripts submitted to Biomedical journals. Authors should include a statement in the manuscript that informed consent was obtained for experimentation with human subjects. The privacy rights of human subjects must always be observed.

All animal experiments should comply with the ARRIVE guidelines and should be carried out in accordance with the EU Directive 2010/63/EU for animal experiments, and the authors should clearly indicate in the manuscript that such guidelines have been followed.
