Abstract
In this paper, limitations of the Schottky Capacitance Spectroscopy (S CS) method are discussed and modifications of the method for low forwa rd bias and high frequency are proposed. It is shown that simplificati ons commonly accepted in the SCS method can lead to erroneous conclusi ons as to the cut-off frequency and hence the interface states paramet ers. A modified SCS method is used in the interface states capacitance measurements in AuPtTi/nGaAs Schottky diodes.
