Fine Structure of Trious and Excitons in Single GaAs Quantum Dots

Abstract

Trions and excitons, localized laterally in quantum-dot-like potentials in GaAs quantum wells, were studied by magnetophotoluminescence spectroscopy as a function of magnetic field strength and orientation. Singletrion spectroscopy was demonstrated using high spatial resolution. We present a comparative study of the fine structure of single localized excitons and trions.
