Photoluminescence and quantum-degenerate exciton states in semiconductors

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Quantum-electrodynamic calculations predict that truly incoherent light can be used to efficiently generate quantum-degenerate exciton population states. Resonant incoherent excitation directly converts photons into excitons with vanishing center of mass momentum. The populated exciton state possesses long-range order, is very stable against perturbations, and should be observable via its unusual directional and density dependence in luminescence measurements.
