Abstract
Photodetectors based on diode heterostracture with InAsSbx photosensitive region (x = 0.38) with long-wave cut-off λ0.1 about 10 μm (296 K) are investigated. The dependences of dark current density and detectivity in the temperature range of 200–425 K have been investigated. It is shown that the experimental samples are characterized by values of dark current density about 500 A/cm2 at room temperature, detectivity 1.2 × 109 and 5 × 109 cm Hz1/2 W–1 at room temperature and 250 K, respectively, and diffusion mechanism of current flow in the temperature range 200–350 K.
期刊介绍：
Optics and Spectroscopy (Optika i spektroskopiya), founded in 1956, presents original and review papers in various fields of modern optics and spectroscopy in the entire wavelength range from radio waves to X-rays. Topics covered include problems of theoretical and experimental spectroscopy of atoms, molecules, and condensed state, lasers and the interaction of laser radiation with matter, physical and geometrical optics, holography, and physical principles of optical instrument making.
