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 mm, at values of stimulating light intensity Ф = 100—400 Lk, electrical field Е = 0.5—130 V/сm and temperature Т = = 265—310 К. 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.
