The device is based on a modified N+pP+ heterostructure grown on 2”., epiready, semi-insulating (100) GaAs substrates in a horizontal MOCVD AIX 200 reactor. The devices were examined by measurements of spectral and time responses as a function of a bias voltage and operating temperatures. The time response was measured with an Optical Parametric Oscillator (OPO) as the source of ~25 ps pulses of infrared radiation, tuneable in a 1.55–16 μm spectral range. Two-stage Peltier cooled devices (230 K) with a 4.1 μm cut-off wavelength were characterized by 1.6 × 1012 cm Hz1/2/W peak detectivity and < 1 ns time constant for V > 500 mV.}, type={Artykuły / Articles}, title={Fast Response Hot (111) HGCDTE MWIR Detectors}, URL={http://www.journals.pan.pl/Content/106314/PDF/10.1515-2017-0044%20paper%2005.pdf}, doi={10.1515/mms-2017-0044}, keywords={HgCdTe, MWIR, photodetector, Response Time}, }
