Abstract

Some technique is presented for IR photocathodes manufacturing on the basis of In_0.53Ga_0.47As/InP heterostructures with Shottky barrier. Discussed is a method for ultra-high vacuum transfer of the photocathodes into vacuum devices. It is shown that the sensitivity of photocathodes in a sealed out device at (lambda) equals 1.55 micrometers is two orders of magnitude higher comparing to the sensitivity of traditional Ag-Cs-O photocathodes. The developed photocathodes may be used in time analyzing image tubes covering the spectral range from 0.9 to 1.7 micrometers .
