Cold Anti-Stokes Photoluminescence of InP Self-Assembled Quantum Dots in the Presence of Electric Current
Abstract
An intense anti-Stokes photoluminescence is observed in a structure with InP quantum dots in the presence of a direct electric current and cw optical pumping below the lowest electron hole transition in the quantum dots. A simple model is proposed for the explanation of the observed phenomenon. Its essential point is the existence of deep level defects around the QDs.
