Single-photon emission from single InGaAs/GaAs quantum dots grown by droplet epitaxy at high substrate temperature

Single-photon emission from single InGaAs/GaAs quantum dots grown by droplet epitaxy at high substrate temperature

The authors report single-photon emission from InGaAs quantum dots grown by droplet epitaxy on (100) GaAs substrates using a solid-source molecular beam epitaxy system at elevated substrate temperatures above 400°C without post-growth annealing. High-resolution micro-photoluminescence spectroscopy e...
