| Summary: | This paper is an introduction to the analysis of the
piezoelectric photoacoustic spectra of single-layer seminductor samples. The
analysis comprises, among other things, the temperature distribution formula
necessary for the computations of the piezoelectric amplitude and phase spectra.
It presents also the procedures of determination of the piezoelectric spectra of
semiconductor materials from the optical absorption coefficient ones and the
influence of many experimental parameters on the piezoelectric spectra for
semiconductors exhibiting either direct or indirect electron type transitions.
The origin of the characteristic structure of the piezoelectric spectra is
analyzed and discussed. |
