AbstractThis paper investigates the robustness of the thermally stimulated current technique as a method to determine the density of states distribution in thin film semiconductors under a wide range of conditions. Numerical simulation is used to solve the non-linear time-dependent rate equations for free and trapped charge in systems with continuous and structured DOS profiles. We explore the derivation of energy and density scales from temperature and conductivity data. We examine for these systems the limits of the method's apparent immunity to varying conditions of strong and weak retrapping, and investigate the corrections required for variations in carrier lifetime with temperature.

Potential Approach

We have applied the full-relativistic Dirac B-Spline R-matrix method to obtain cross sections for electron scattering from ytterbium atoms. The results are compared with those obtained from a semi-relativistic (Breit-Pauli) model-potential approach and the few available experimental data.

A summary is presented of the processes by which low energy electrons lose energy in moving through the atmosphere and estimates are given of the cross sections and energy loss rates. The mechanisms by which thermal electrons cool are described and the cooling efficiencies are listed.
