Dielectric response of electron-hole systems. Nondegenerate case and quantum corrections
arXiv:2108.07733 · doi:10.1088/1361-648X/ac2062
Abstract
Analytical results for the dielectric function in RPA are derived for three-, two-, and one-dimensional semiconductors in the weakly-degenerate limit. Based on this limit, quantum corrections are derived. Further attention is devoted to systems with linear carrier dispersion and the resulting Dirac-cone physics.
