Si-Doped InAs/GaAs Quantum Dot Solar Cell with Alas Cap Layers

open access: yesE3S Web of Conferences, 2017
In this work, the effect of Si doping on InAs/GaAs quantum dot solar cells with AlAs cap layers is studied. The AlAs cap layers suppress the formation of the wetting layer during quantum dot growth.

Frequency-Stabilized Source of Single Photons from a Solid-State Qubit

open access: yesPhysical Review X, 2013
Single quantum dots are solid-state emitters that mimic two-level atoms but with a highly enhanced spontaneous emission rate. A single quantum dot is the basis for a potentially excellent single-photon source.

A single-electron probe for buried optically active quantum dot

open access: yesAIP Advances, 2012
We present a simple method that enables both single electron transport through a self-assembled quantum dot and photon emission from the dot. The quantum dot buried in a semiconductor matrix is electrically connected with nanogap electrodes through ...
