Magnetic field evolution of spin blockade in Ge/Si nanowire double quantum dots

We perform transport measurements on double quantum dots defined in Ge/Si core/shell nanowires and focus on Pauli spin blockade in the regime where tens of holes occupy each dot. We identify spin blockade through the magnetic field dependence of the leakage current. We find both a dip and a peak in...
