Abstract

Photodetectors based on diode heterostracture with InAsSb_x photosensitive region (x = 0.38) with long-wave cut-off λ_0.1 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 Hz^1/2 W^–1 at room temperature and 250 K, respectively, and diffusion mechanism of current flow in the temperature range 200–350 K.

基于 InAsSb0.38 固溶体的长波（λ0.1 = 10 μm，296 K）红外光探测器

摘要研究了基于 InAsSbx 光敏区（x = 0.38）的二极管异质断裂的光电探测器，其长波截止点 λ0.1 约为 10 μm (296 K)。研究了暗电流密度和检测率在 200-425 K 温度范围内的相关性。结果表明，实验样品在室温下的暗电流密度值约为 500 A/cm2 ，在室温和 250 K 下的探测率分别为 1.2 × 109 和 5 × 109 cm Hz1/2 W-1，在 200-350 K 的温度范围内的电流流动机制为扩散机制。
