Trajectory Analyses of Electron Transport Propertiesνnder Anisotropy in Elastic and Inelastic Scatterings

抄録

Electron transport properties in gases, suffering anisotropic scatterings, elastic and inelastic, have been precisely calculated using the Extended FTI method and the Monte-Carlo simulation. Not only the transverse diffusion coefficient which changes with anisotropy in the elastic scattering, the mean energy and the drift velocity have also been found to vary with the degree of anisotropy in the inelastic scatterings. Therefore, it has been understood that the procedures of the Boltzmann equation analyses being currently used to obtain the electron transport properties are strictly valid only under complete isotropy in scatterings.
