Abstract
As a continuation of earlier work, we present the results of a local-density-approximation-based calculation of some dielectric properties of silicon. In particular, we have calculated the plasmon-resonance line shape for k→0 and the plasmon dispersion curves including local-field effects and exchange-correlation corrections. The results are compared with both our earlier empirical-pseudopotential results and experimental data.Keywords
