تأثير معاملات البيزوكهربائية على الصور الفونونية لبلورات أشباه الموصلات المكعبة

Abstract EN

In this paper, the effect of piezoelectric parameters on the phonon focusing of some semiconductor cubic crystals has been studied.

These properties has an evident effect on the transverse modes of the phonon focusing images for these crystals these effect is increased as the factor k44 of these crystals is increased.

Numerically two methods for computing the phonon focusing images has been applied in this work, the first depends upon the detailed calculations of group velocity while the second method (suggested algorithm) depends upon the calculation of direction of group velocity from the slowness surface only, the suggested algorithm has been tested with piezoelectric and when the piezoelectric properties is ignored.
