CdTe/Langmuir-film m.i.s. structures

Langmuir films based on cadmium stearate have been successfully deposited on to the surface of p-type CdTe. The measured C/V curves show, for the first time, the accumulation, depletion and weak-inversion regions typical of an ideal device. The G/V curves show a sharp peak in the depletion region at high frequencies which is thought to be due to losses at interface states. An initial estimate of the density yields an average value of 1011 states cm¿2.
