Temperature-Dependent Exciton Dynamics in a Single GaAs Quantum Ring and a Quantum Dot
Micro-photoluminescence was observed while increasing the excitation power in a single GaAs quantum ring (QR) at 4 K. Fine structures at the energy levels of the ground (N = 1) and excited (N = 2) state excitons exhibited a blue shift when excitation power increased. The excited state exciton had a...
