Abstract

Spectral analysis of pZnSb-nCdTe heterostructures (HS) obtained by a laser-pulse epitaxy method has shown that such HS exhibit photo-sensitivity beyond the absorption edge at T=78 K for a narrowband semiconductor. Up to a wavelength λ=7μm [1]. This photo-sensitivity value is only 6 times smaller than its maximum at a fundamental absorption wavelength λ=4.3μm. Due to HS thickness, this effect cannot be explained by the usual tunneling
