Opto-Electronics Review | 2020 | 28 | 3


Graphene applications in electronic and optoelectronic devices have been thoroughly and intensively studied since graphene discovery. Thanks to the exceptional electronic and optical properties of graphene and other two-dimensional (2D) materials, they can become promising candidates for infrared and terahertz photodetectors.

Quantity of the published papers devoted to 2D materials as sensors is huge. However, authors of these papers address them mainly to researches involved in investigations of 2D materials. In the present paper this topic is treated comprehensively with including both theoretical estimations and many experimental data.

At the beginning fundamental properties and performance of graphene-based, as well as alternative 2D materials have been shortly described. Next, the position of 2D material detectors is considered in confrontation with the present stage of infrared and terahertz detectors offered on global market. A new benchmark, so-called “Law 19”, used for prediction of background limited HgCdTe photodiodes operated at near room temperature, is introduced. This law is next treated as the reference for alternative 2D material technologies. The performance comparison concerns the detector responsivity, detectivity and response time. Place of 2D material-based detectors in the near future in a wide infrared detector family is predicted in the final conclusions.

In this work, we present an extensive investigation of the effect of Al2O3 decoration on the morphological, structural and opto-electronic properties of a porous Si (Sip)/Cr2O3 composite. The Sip layers were prepared by the anodization method. Al2O3 and Cr2O3 thin films were deposited by physical vapour deposition. The morphological and micro-structural properties of Sip/Cr2O3/Al2O3 were studied using the scanning electron microscope, energy dispersive X-ray spectroscopy and X-ray diffraction techniques. It was found that Al2O3 decoration with different concentration strongly affects the Sip/Cr2O3 microstructure mainly at the level of porosity. Variable angle spectroscopic ellipsometry demonstrates a strong correlation between optical constants (n and k) of Sip/Cr2O3/Al2O3 and microstructure properties. Dielectric properties of Sip/Cr2O3/Al2O3 such as electrical conductivity and conduction mechanism were explored using impedance spectroscopy over the temperature interval ranging from 340 to 410°C. A semiconductor to the metallic transition has been observed at high frequency.

In this paper, we present the electrical and electro-optical characterizations of an InAs/GaSb type-2 superlattice barrier photodetector operating in the full longwave infrared spectral domain. The fabricated detectors exhibited a 50% cut-off wavelength around 14 μm at 80 K and a quantum efficiency slightly above 20%. The dark current density was of 4.6 × 10 2 A/cm2 at 80 K and a minority carrier lateral diffusion was evaluated through dark current measurements on different detector sizes. In addition, detector spectral response, its dark current-voltage characteristics and capacitance-voltage curve accompanied by electric field simulations were analyzed in order to determine the operating bias and the dark current regimes at different biases. Finally, dark current simulations were also performed to estimate a minority carrier lifetime by comparing experimental curves with simulated ones.

The paper presents a dual-band plasmonic solar cell. The proposed unit structure gathers two layers, each layer consists of a silver nanoparticle deposited on a GaAs substrate and covered with an ITO layer, It reveals two discrete absorption bands in the infra-red part of the solar spectrum. Nanoparticle structures have been used for light-trapping to increase the absorption of plasmonic solar cells. By proper engineering of these structures, resonance frequencies and absorption coefficients can be controlled as it will be elucidated. The simulation results are achieved using CST Microwave Studio through the finite element method. The results indicate that this proposed dual-band plasmonic solar cell exhibits an absorption bandwidth, defined as the full width at half maximum, reaches 71 nm. Moreover, It can be noticed that by controlling the nanoparticle height above the GaAs substrate, the absorption peak can be increased to reach 0.77.

The paper presents a comprehensive look at the perspectives on the use of THz in digital communication systems. The publication aims to focus on arguments that justify a significant increase in the frequency of radio links and their integration with fibre-based networks. Comparison of THz links with their microwave and optical counterparts is discussed from basic physical limitations to technological constraints. Main attention is paid to the available channel capacity resulting from its bandwidth and signal-to-noise ratio. The short final discussion is about technology platforms that seem to be crucial to the availability of suitable THz sources. According to the author, the biggest advantage of using bands in the range of several hundred GHz for a digital data transmission is their use for mobile communication over short distances, as well as for broadband indoor links. However, these applications require a development of compact electronic THz sources with low noise and power reaching single watts. This is beyond the range of the most popular silicon-based technology platform, although a significant progress can be expected with the development of technologies based on wide bandgap semiconductors. Fibre optic connections remain the unquestioned leader in communication over long distances and permanent links.

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.

• 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.


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.
