A site-controlled quantum dot system offering both high uniformity and spectral purity
A site-controlled quantum dot system offering both high uniformity and spectral purity
In this letter we report on the optical properties of site-controlled InGaAs quantum dots with GaAs barriers grown in pyramidal recesses by metalorganic vapor phase epitaxy. The inhomogeneous broadening of excitonic emission from an ensemble of quantum dots is found to be unusually narrow, with a standard deviation of 1.19 …
