Dynamic interaction of bulk acoustic waves with a 2DEG at a GaAs/AlGaAs heterojunction in a strong magnetic field. Elastic field distribution.

Abstract

The results of a theoretical and experimental study of the interaction of longitudinal coherent bulk acoustic waves at 9.4GHz with a 2-DEG at a GaAs/AlGaAs heterojunction in a strong magnetic field are given. A generalized transfer matrix formalism was used to consider such a dynamic interaction in a piezoelectric medium and hence to analyze the mode composition of the elastic fields in the layered dissipative structure.
