Paper Abstract

Properties of n-epilayer InAs-SiO2 interface with various chemical treatments of InAs surface have been studied. Epilayer InAs films (Nd equals 1015 cm-3) of 5 - 7 micron thickness has been grown on n+-substrate with doping level 3.1018 cm-3. High quality properties of MIS-structures have been observed: surface state density < 1011 cm-2 eV-1, flat band voltage 2 - 5 V for SiO2 120 nm thickness. The array of photosensitive 128 X 128 MIS-structures with In2O3 gate has been mounted on silicon readout multiplexer by flip-chip method. The detectivity of InAs-cells in range of temperatures 80 - 100 K is more than 2(DOT)1012 cmHz1/2W-1.
