Abstract

A nonlinear Thomas‐Fermi dielectric function is derived for semiconductors in the framework of the Resta model. When the concept of an effective impurity charge is introduced to ensure the correct screening radius, the analytical dielectric function agrees excellently with the exact numerical solution.

In the application of the optimized Thomas-Fermi theory to condensed phase systems, it has proved convenient to introduce a sum of atom-centered functions to represent the most rapidly varying part of the electron density near the nuclei. By extraction of this portion of the density, attention can b
