Abstract
The negative infrared photoconductivity (NPH) has been observed for the first time in CdS1-xSex films, in the wavelength region of 0.700 ÷ 1.23 μm. at values of stimulating light intensity Φ = 100 ÷ 400 Lk. electrical field E = 0.5 ÷ 130 V/cm and temperature T = 265 ÷ 310 Κ. It is established, that basic laws of NPH explains on the basis of two-barrier model and in the considered conditions a charge carriers, overcome a barrier by tunneling. A films of CdS1-xSex can be used in IR engineering and negatronics.
