Resonant and Off‐Resonant Light–Matter Interaction in Semiconductors Kinetics and Transients
R. Zimmermann, Michael Hartmann
Abstract
Abstract Kinetic problems for off‐resonance excitation (dynamical Stark effect) and resonant excitation (laser‐induced gaps) are studied. Within the Hartree‐Fock theory, Stark shift and bleaching of the exciton line are evaluated. The influence of photon statistics on light‐induced gaps is investigated. Open questions concerning the transient response are clarified.
