Electron transfer between semiconductor quantum dots via laser-induced resonance transitions

Abstract

The effect of a resonant laser pulse on the quantum dynamics of an electron in a system of two semiconductor quantum dots (QDs) is studied theoretically. The pulse characteristics (frequency, amplitude, and duration) corresponding to the highest probability of electron transition from the ground state of one QD to the ground state of the other QD are determined with regard to possible difference in the QD sizes. A specific model with QDs of near cubic shape is considered.
