Photoluminescence enhancement by deterministically site-controlled, vertically stacked SiGe quantum dots
Jeffrey Schuster, Johannes Aberl, Lada Vukušić +5
The Si/SiGe heterosystem would be ideally suited for the realization of complementary metal-oxide-semiconductor (CMOS)-compatible integrated light sources, but the indirect band ga…
Zero field splitting of heavy-hole states in quantum dots
G. Katsaros, J. Kukučka, L. Vukušić +5
Using inelastic cotunneling spectroscopy, we observe a 55μeV zero field splitting in the spin triplet manifold of Ge hut wire quantum dots. The degeneracy of the heavy hole triplet…
Single-shot readout of hole spins in Ge
Lada Vukušić, Josip Kukučka, Hannes Watzinger +3
The strong atomistic spin orbit coupling of holes makes single-shot spin readout measurements difficult because it reduces the spin lifetimes. By integrating the charge sensor into…
Ge hole spin qubit
Hannes Watzinger, Josip Kukučka, Lada Vukušić +5
Holes confined in quantum dots have gained considerable interest in the past few years due to their potential as spin qubits. Here we demonstrate double quantum dot devices in Ge h…
Fast Hole Tunneling Times in Germanium Hut Wires Probed by Single-Shot Reflectometry
Lada Vukušić, Josip Kukučka, Hannes Watzinger +1
Heavy holes confined in quantum dots are predicted to be promising candidates for the realization of spin qubits with long coherence times. Here we focus on such heavy-hole states…
