Kinetic theory of parametric excitation of acoustic waves in piezoelectric semiconductors
A K Sundaram P K Kaw S K Sharma
Using a kinetic description for electrons and the usual equation of motion for lattice displacement we have derived a general dispersion relation for acoustic waves in a piezoelectric semiconductor, in the presence of a strong high frequency electric field oscillating near the electron plasma frequency. Earlier hydrodynamic results valid for

Velocity gradient driven flute instabilities in plasmas
The effect of velocity gradient across the magnetic field on the low frequency flute modes is examined in detail, using the normal mode analysis. It is shown that some new type of instabilities driven primarily by the velocity
