Highly tuneable hole quantum dots in Ge-Si core-shell nanowires
Matthias Brauns, Joost Ridderbos, Ang Li +3
We define single quantum dots of lengths varying from 60 nm up to nearly half a micron in Ge-Si core-shell nanowires. The charging energies scale inversely with the quantum dot len…
Anisotropic Pauli spin blockade in hole quantum dots
Matthias Brauns, Joost Ridderbos, Ang Li +3
We present measurements on gate-defined double quantum dots in Ge-Si core-shell nanowires, which we tune to a regime with visible shell filling in both dots. We observe a Pauli spi…
Electric-field dependent g-factor anisotropy in Ge-Si core-shell nanowire quantum dots
Matthias Brauns, Joost Ridderbos, Ang Li +2
We present angle-dependent measurements of the effective g-factor g* in a Ge-Si core-shell nanowire quantum dot. g* is found to be maximum when the magnetic field is pointing perpe…
