Abstract
Annealings have been performed on Ge0.84Sn0.16 microstructures in order to improve their optical properties by reducing the number of defects at the origin of Sn segregation. An enhancement of the photoluminescence intensity by a factor of 2.4 for annealed microstructures compared to ones without annealing was for instance achieved. Different annealing temperatures were tested to limit Sn segregation above the epitaxy temperature.
