Abstract

Analysis of quantum dot structures is a current topic with important applications in solid-state digital logic design, quantum information technology and quantum optics. In this work, we show a variational formulation for the solution of the effective two-level approach of the analysis of electron localization in two coupled quantum dots. Numerical results are presented as well the use of electron localization in the realization of a configurable logic circuit using quantum-dot cellular automata.
