TLDR
In this paper, the Boltzmann transfer equation for free carriers has been investigated for harmonic generation in bismuth and the results are compared with the experimental results of Bate and Wisseman for damped Alfven wave second-harmonic generation.Abstract:
The possible nonlinear mechanisms for harmonic generation in bismuth have been investigated by solving the Boltzmann transfer equation for free carriers. Space diffusion of carriers has been shown to be as important as the interaction of magnetic field of the wave with current density. The results are compared with the experimental results of Bate and Wisseman for damped Alfven wave second‐harmonic generation. Except for the behavior of harmonic power with static magnetic field, a good agreement is found.read more

Hot carrier anisotropic conductivity of a current-carrying bismuth
S.C. Kaushik,V.K. Tripathi +1 more
TL;DR: In this paper, the hot carrier effects and d.c. conductivity of a semi-metal (e.g. Bismuth) have been studied by using the semi-kinetic treatment and the effective temperature model.

Self−focusing of electromagnetic beams in bismuth
D P Tewari,Awdhesh Kumar +1 more
TL;DR: In this article, an intense Gaussian electromagnetic beam propagating through bismuth gives rise to the heating and redistribution of electrons and holes, and hence self-induced focusing occurs.

Stimulated Raman scattering of sub-millimeter waves in bismuth
Pawan Kumar,V.K. Tripathi +1 more
TL;DR: In this article, a high-power sub-millimeter wave propagating through bismuth, a semimetal with non-spherical energy surfaces, parametrically excites a space-charge mode and a backscattered electromagnetic wave.

Transport and Deformation-Potential Theory for Many-Valley Semiconductors with Anisotropic Scattering
Conyers Herring,Erich Vogt +1 more
TL;DR: In this article, a transport theory which allows for anisotropy in the scattering processes is developed for semiconductors with multiple nondegenerate band edge points, and the main effects of scattering on the distribution function over each ellipsoidal constant-energy surface can be described by a set of three relaxation times, one for each principal direction; these are the principal components of an energy-dependent relaxation-time tensor.
