Photoluminescence from an Ensemble of Self-Assembled Quantum Dots: Cooperative Effects

Not Accessible

Your library or personal account may give you access

Abstract

Optical properties of self-assembled quantum dots (SAQD) have attracted much interest during recent years. With a typical size of the order of the Bohr radius, SAQD’s are essentially zero-dimensional objects sustaining only a few excitonic states. Given a high in-plane density, 1010 - 1012 cm−2, an array of SAQD’s can be viewed as a 2D system of artificial atoms with a narrow distribution of excitation energies.
