Homogeneous Linewidths in the Optical Spectrum of a Single Gallium Arsenide Quantum Dot
TL;DR: The homogeneous linewidths in the photoluminescence excitation spectrum of a single, naturally formed gallium arsenide (GaAs) quantum dot have been measured with high spatial and spectral resolution and provide a new perspective on the dephasing dynamics of the exciton in a quantum-confined, solid-state system.
