Title:The effect of elastic and inelastic scattering on electronic transport in open systems
Subtitle: Group publication title: Subject and Keywords:kinetic equation ; relaxation time approximation ; scattering processes
Abstract:The purpose of this study is to apply the distribution function formalism to the problem of electronic transport in open systems, and to numerically solve the kinetic equation with a dissipation term. This term is modeled within the relaxation time approximation and contains two parts, corresponding to elastic or inelastic processes. The collision operator is approximated as a sum of the semi-classical energy dissipation term and the momentum relaxation term, which randomizes the momentum but does not change the energy. ; As a result, the distribution of charge carriers changes due to the dissipation processes, which has a profound impact on the electronic transport through the simulated region discussed in terms of the current - voltage characteristics and their modification caused by the scattering. Measurements of the current - voltage characteristics for titanium dioxide thin layers are also presented, and compared with the results of numerical calculations.
