Research Abstract

In this study, we have developed a single photon emitter with single electron transistor. The aim is to control number of electrons in a dot before emitting single photons. We have succeeded in fabricating a single electron device based on a quantum dot with a capping layer. We have shown a gate controlled photoluminescence and photocurrent from the dots embedded in the device structure.
