Quantum Dot and Nanopore lasers

AFM Image of patterned quantum dots

 Recently much effort has gone towards understanding quantum dots (QD) so that quantum circuits and devices may be realized. As the field of quantum computing emerges, the driving force towards understanding these unique structures becomes apparent. We have worked on key concepts of InAs QD growth by metalorganic chemical vapor deposition (MOCVD) and developed method of selective QD epitaxy using strained InGaAs thin films and nanoscale oxide patterned masks.
