Abstract

Abstract: The Negative Differential Conductivity and Transient Negative Mobility effects in xenongas are analyzed by a first-principles particle simulation technique and via anapproximate solution of the Boltzmann transport equation (BE). The particle simulationmethod is devoid of the approximations that are traditionally adopted in the BE solutionsin which: (i) the distribution function is searched for in a two-term form; (ii) theCoulomb part of the collision integral for the anisotropic part of the distributionfunction is neglected; (iii) Coulomb collisions are treated as binary events; and (iv) therange of the electron-electron interaction is limited to a cutoff distance. The resultsobtained from the two methods are, for both effects, in good qualitative agreement, smalldifferences are attributed to the approximations listed above.
