Summary on Grant Application Form |
|
A semiconductor quantum dot is a nano-sized island of one semiconductor surrounded by a sea of another semiconductor with large bandgap. The quantum dot has discrete energy levels, just like an atom, and has potentially ideal materials properties for controlling and manipulating quantum states, a crucial goal in contemporary science. The proposer has already demonstrated that the charge on an individual quantum dot can be controlled simply by the voltage applied to a gate electrode in a specially constructed device. However, these devices have large total area and only dc voltages are applied. New functionality arises if fast (GHz) pulses are applied to small area devices. It now becomes possible to control the occupation of electrons and holes in the time domain. There are many applications once the materials science and fast electronics technology are under control. These include voltage-triggered single photon emission, manipulation of the dark and bright excitons and manipulation of spin
