Abstract
Abstract
The results of a study of multilayer photodiodes based on InAs1-
x
Sb
x
solid solutions (0.3 < x <0.4), with a long-wavelength cut-off of λ
0.1
≈ 11 μm at room temperature are presented. The current-voltage and spectral characteristics of photosensitivity and electroluminescence were analyzed in the temperature range of 80 ÷ 300 K. Experimental samples of photodetectors are characterized by a quantum efficiency of 0.23 at 150 K and a diffusion mechanism of current flow at least in the 200-300 K range. The detectivity of the immersion lens PD at the maximum has values of at least D*8 µm = 8·108 and D*
5.5 µm = 1010 cm·Hz1/2W-1 at 300 and 150 K, respectively.
