The transport properties of the perovskites KTaO3 are calculated using first-principles methods. Our study is based on Boltzmann transport theory and the relaxation time approximation, where the scattering rate is calculated using an analytical model describing the interactions of electrons and longitudinal optical phonons. We compute the room-temperature electron mobility and Seebeck coefficie...

Abstract This paper discusses a novel “chaotic” form of superbanana transport, and compares theory to experiments on nonneutral plasmas. Superbanana transport is caused by particles that cross local trapping separatrices (magnetic or electric ripples) in the presence of field “errors” such as toroidal magnetic curvature. Traditionally, collisions (at rate ν) cause separatrix crossings, with res...

A comprehensive investigation of electron transport in N2–O2 mixtures has been carried out using a multi term theory for solving the Boltzmann equation instead of conventional two term theory often employed in plasma modeling community. We focus on the way in which the transport coefficients and spatially resolved transport data are influenced by the amount of O2 in the mixture. Emphasis is pla...

Abstract In the presence of a strong electric field perpendicular to magnetic field, electron cross-field (E × B) flow relative unmagnetized ions can cause so-called cyclotron drift instability (ECDI) due resonances ion acoustic mode and harmonics. This occurs in, for example, collisionless shock ramps in space, E B discharge devices such as Hall thrusters. A prominent feature ECDI is its capab...
