Deep Level Fourier Spectroscopy for Determination of Deep Level Parameters

Japanese Journal of Applied Physics, 1982
A new technique called deep-lebel Fourier spectroscopy (DLFS), is proposed. This is an efficient and convenient method for evaluating deep livels in semiconductors. The technique is presented with a frequency space analysis for the case of exponential capacitance transients. Taking the Fourier transforms of the transient capacitance values, the deep

Deep levels in GaAs:V

High Pressure Research, 1992
Abstract The influence of hydrostatic pressure on vanadiumrelated acceptor level in GaAs has been investigated in order to test the possibility of using it as a suitable reference level in heterojunctions. The impedance measurements made on GaAs:V/Ni Schottky barriers give its pressure coefficient of +110 meV/GPa with respect to the conduction band ...
