Excitonic electroabsorption and electrorefraction in semiconductors

Abstract

Electron-hole correlations dictate in large measure the form of the absorption edge in semiconductors. As such, the inclusion of the Coulomb interaction is essential to any calculation of the optical constants in that spectral region. In this paper we consider the absorption-coefficient and refractive index changes induced by a static electric field accounting for the Coulomb interaction. We present a solution to the excitonic electroabsorption problem based on a power-series solution of the exact effective-mass equation. This technique eliminates the use of the computationally intensive numerical integrations that previous authors have employed.1-6
