The Schottky barrier contribution to photoacoustic effect in Au-Si system

The photoacoustic effect in metal-semiconductor system, i.e., the influence of Schottky barrier on the thermal and electronic transport processes in semiconductor was investigated. The amplitude and phase spectra were measured for dependence on the modulation frequency of excitation optical beam, us...

Description
Summary:The photoacoustic effect in metal-semiconductor system, i.e., the influence of Schottky barrier on the thermal and electronic transport processes in semiconductor was investigated. The amplitude and phase spectra were measured for dependence on the modulation frequency of excitation optical beam, using the PA frequency transmission technique. Thermal, elastic and electronic transport parameters were obtained by the analysis of experimental and theoretical PA signals, including the Schottky barrier effect, for a metal film-semiconductor substrate sample.
