Zusammenfassung
We present Coulomb blockade measurements of two few-electron quantum dots in series configured such that the electrochemical potential of one of the two dots was aligned with spin-selective leads. Charge transfer through the system required cotunneling through the second dot (which was not in resonance with the leads). The amplitude modulation of the current was found to reflect spin blockade ...
Zusammenfassung
We present Coulomb blockade measurements of two few-electron quantum dots in series configured such that the electrochemical potential of one of the two dots was aligned with spin-selective leads. Charge transfer through the system required cotunneling through the second dot (which was not in resonance with the leads). The amplitude modulation of the current was found to reflect spin blockade events occurring at either of the two dots. We also confirm that charge redistribution events that occurred in the off-resonance dot could be detected indirectly via changes in the electrochemical potential of the aligned dot.
