We report an experimental study of the electrical properties of the interface between the Al(2)O(3)passivating coating grown by plasma enhanced atomic layer deposition at different temperatures and thep-CdHgTe (x(CdTe)= 0.22) coating grown by molecular beam epitaxy via measuring theC-Vcharacteristics of MIS structures. It has been established that, at an Al(2)O(3)growth temperature of 200 degrees C, the concentration of acceptors in CdHgTe increases due to dissociation and, at a temperature of 80 degrees C, the spread of the insulator capacitance and built-in charge increases. The optimum temperature for growing the passivating Al(2)O(3)coating on CdHgTe lies in the range of 120-160 degrees C.
