Process of transfer of electrons in a gallium arsenide
running-wave amplifier with a Schottky barrier has been
investigated. Simulation of the process has been
implemented by the Monte Carlo method with the use of
the three-valley (GammaLX) model of the GaAs conduction band
with account for the nonparabolicity of the bands,
scattering on phonons, and transport between valleys.
The increment of spatial-charge wave (SCW) has been
calculated; it has been shown that the amplification in
such a device can be substantially greater than in
a beam-instability amplifier.
