Ab initio calculation of excitonic effects in the optical spectra of semiconductors / S. Albrecht, L. Reining, R. Del Sole, G. Onida. - In: PHYSICAL REVIEW LETTERS. - ISSN 0031-9007. - 80:20(1998), pp. 4510-4513.
Abstract:
An ab initio approach to the calculation of excitonic effects in the optical absorption spectra of semiconductors and insulators is formulated. It starts from a quasiparticle band structure calculation and is based on the relevant Bethe-Salpeter equation. An application to bulk silicon shows a substantial improvement with respect to previous calculations in the description of the experimental spectrum, for both peak positions and line shape.
