Zener oscillations

This work discusses the periodic motion, called Zener oscillation, of a crystal in a uniform steady applied field. Semiclassical electron wave packets are constructed in the Stark and Houston one-band representations and show that they are periodic with the Zener period. Quasicoherent states localized in both position and momentum with minimized fluctuations are determined. The Zener oscillation spectrum of a GaAs conduction electron, the spectrum's stability under directional deviations, and the electron's electromagnetic coupling are computed.
