Low-Density InGaAs/AlGaAs Quantum Dots in Droplet-Etched Nanoholes. [PDF]

Nano Lett
Over the past two decades, epitaxial semiconductor quantum dots (QDs) have demonstrated very promising properties as sources of single photons and entangled photons on-demand. Among different growth methods, droplet etching epitaxy has allowed the growth of almost strain-free QDs, with low and controllable surface densities, small excitonic fine ...
