Acoustomagnetoelectric effect in a degenerate semiconductor with nonparabolic energy dispersion law

Surface (2D) acoustomagnetoelectric effect (SAME) and bulk (3D) acoustomagnetoelectric effect (AME) have been studied in a degenerate semiconductor with nonparabolic energy dispersion law. Expressions are obtained for the acoustomagnetoelectric fields i.e. SAME E and AME E under weak wt <<1 and strong (wt >>1) magnetic fields. It is shown that SAME E and AME E depend on the nonparabolicity parameter (h) in a complex manner. Unlike AME E which changes sign when the magnetic field H is reversed for SAME E this phenomenon occurs whenever q satisfies the condition p <q <p
