| Abstract/Description: | Electron transport in single lateral quantum dot (QD) and parallel lateral doublequantum dot (DQD) systems is modeled using semiclassical rate equations. The Zeemaneffect, in conjunction with resonant tunneling, is used to select the spin of electronsinvolved in transport. We show adiabatic spin pumping by periodic variation of thesystems' confining parameters, namely the quantum point contacts (QPCs) dictating theboundaries of the dots, and the gate voltage applied to each dot. The limitations ofadiabatic spin pumping are subsequently examined by counting the average spin pumpedper cycle when frequency and interdot capacitance are adjusted. | |
