Recent Progress In The Development Of Mct Hot Detectors

To push HOT-performance, AIMs existing n-on-p technology has been improved by introducing Gold as an acceptor and reducing its concentration to the lower 1015/cm(3) range as well as by optimizing the passivation process. This results in a substantial reduction in dark current density, a prerequisite for HOT operation. Recent dark current data are compared to ones previously obtained as well as to Tennant's Rule07 [1], a generally accepted bench mark in this context.Furthermore, we present electro-optical parameters obtained in the temperature range from 120 K to 170 K on resulting FPAs with 640x512 pixels, a pitch of 15 mu m and a typical (80 K) cutoff wavelength of 5.1 mu m.
