TLDR
In this paper, the third harmonic components in the reflected and transmitted waves produced by nonlinear interaction of a plane-polarized electromagnetic wave with a semiconducting sample of finite thickness have been studied.Abstract:
Third harmonic components in the reflected and transmitted waves produced by non-linear interaction of a plane-polarized electromagnetic wave with a semiconducting sample of finite thickness have been studied. It is found that the sample thickness should be a little less than half the skin depth at the fundamental frequency for optimum harmonic output.read more

Anisotropy of the Conductivity of n -Type Germanium at High Electric Fields
TL;DR: In this article, the drift velocity of a single valley and the change of intervalley scattering rate as a function of applied field were deduced for germanium with respect to current density vs electric field in the [100, [110, and [111] crystallographic directions.

Microwave Frequency Multiplication by Hot Electrons
TL;DR: In this article, an experimental study was made of microwave frequency multiplication observed in germanium at power levels of several kW using a fundamental frequency of 9.4 Gc/sec, a third harmonic yield of about 1% was found.

Non-linear generation of combination frequencies in a plasma
M S Sodha,P K Kaw +1 more
TL;DR: In this article, the authors considered the generation of combination frequencies due to two strong uniform parallel electric fields of frequencies ω1 and ω2 in a homogeneous plasma; it is found necessary to introduce terms containing exp {i(ω 1 ± ω 2)t} in fo (the symmetrical part of the distribution function f) and f2 (the higher-order asymmetrical part appearing as the third term in a Legendre polynomial expansion of f), because their contributions to the combination frequency components of current density are appreciable.
