AMPLIFICATION AND DISPERSION OF OPTICAL PHONONS IN POLAR SEMICONDUCTORS

The interaction between conduction electrons and optical phonons is studied. It is shown that as soon as the electron drift velocity exceeds the phase velocity of the phonons an instability occurs which appears to be strong enough to overcome damping effects. The dielectric constant of the electrons...
