Investigation of the surface state distribution profile in C d S using the acoustoelectric effect
Surface acoustic waves propagating in a piezoelectric substrate can interact with the charge carriers in a semiconductor by means of the electric field which accompanies them. One effect which appears in such an interaction is the transverse acoustoelectric effect, which ca be used to determine the surface state spatial distribution profile. This paper reports on the use of this method to study the surface of a high resistivity CdS specimen
A refined asymptotic model of fluid-structure interaction in scattering by elastic shells is proposed. The model takes into consideration transverse compression of a shell by a fluid and some other phenomena. As an illustration, scattering of a plane acoustic wave by a circular cylindrical shell is considered. Comparison of numerical data corresponding various approximate approaches is provided.
