ELECTRON OSCILLATIONS IN A QUANTUM DOT SYSTEM – NUMERICAL ANALISIS


Abstract

Electron oscillations phenomena in a system composed of two quantum dots and two leads coupled in series has been analysed. The mathematical model of the discussed system is based on the equation of motion method for appropriate correlation functions. The Coulomb interactions between electrons localised on quantum dots and electron spin have been take into account in the calculations. The influence of the selected system parameters on a time-dependent probability of quantum dot energy level occupation has been researched.
