Acoustoelectronic phenomena in low-dimensional conductors in a magnetic field

Attenuation of acoustic waves in layered conductors with a quasi-two-dimensional electron energy spectrum is investigated theoretically in a magnetic field such that the radius of curvature of the charge carrier trajectory is much smaller than the mean free path, but considerably larger than the acoustic wavelength. It is shown that under these conditions acoustic transparency is observed along the layers for certain values of the magnetic field orthogonal to the acoustic wave vector. The role of the Fermi-liquid interaction between conduction electrons in magnetoacoustic effects typical of quasi-two-dimensional conductors is considered.

Intra-collisional field-effect modifications to inter-valley scattering in semiconductors

The field-dependence of the intra-collisional carrier trajectory for non-equivalent inter-valley scattering in semiconductors is shown to induce an effective shift in the valley separation.
