We present a cross-sectional scanning tunneling microscopy STM study of heterogeneous- droplet-epitaxy HDE-grown InGaAs quantum dots QDs. We found that the structural …
A one step method for the production of quantum dots is presented. The method exploits the mismatch strain of molecular beam epitaxy (MBE) deposited InGaAs on GaAs to induce a …
Annealing of InGaAs quantum dots (QDs) fabricated by metal-organic chemical vapour deposition and covered with a very thin GaAs cap layer completely eliminates large …
