Bleustein–Gulyaev waves in gallium arsenide and other piezoelectric cubic crystals

摘要

This paper presents an analytical solution to the boundary‐value problem for the existence of a Bleustein–Gulyaev piezoelectric surface wave in cubic crystals. A general formulation of the boundary‐value problem is first developed. The results are then used to demonstrate the existence of a Bleustein–Gulyaev wave in piezoelectric cubic crystals of 4¯3mand 23 symmetry classes. Numerical solutions are obtained for a number of commonly used materials such as GaAs, GaP, InSb, InAs, Bi12GeO20and Bi4Ge3O12.
