Abstract
The Weinreich relation for longitudinal sound waves is derived from a general standpoint and it is pointed out that in weak collision cases an anisotropic structure of the Fermi surface reveals itself in the anisotropy of the acousto-electric effect. It is then shown that the same results follow for transverse cases when an allowance is made for the fact that the local Hall fields generated by a sound wave can yield a net electric current in the propagation direction of the wave.Keywords
