Coulomb Blockade In Multivalley Si Quantum Dots

Transport properties are fundamental and main means to characterize a quantum dot(QD).We have theoretically developed a general formalism,by generalizing the already existing theory from quantum kinetics and making it applicable more widely,and taking many-body wave functions into consideration,to describe the electronic transport in QDs with a few electrons,consistent with the Fermi golden rule and applied it to the research on quantum Coulomb blockade oscillations in multivalley Si single QD,which is found,in the linear response regime,to possibly be affected by the phase factor due to the Valley-Orbit Coupling(VOC)under appropriate conditions.Moreover,the method can naturally give the result that the spacings between nearest oscillation peaks are not equidistant,as opposite to the case of classical Coulomb blockade,which is the improvement of the already existing formalism.Besides,its application to the similar problem in multivalley Si double QDs(DQD)is highly promising to give us interesting results.
