Nuclear spin-free 70Ge/28Si70Ge quantum well heterostructures grown on industrial SiGe-buffered wafers
P. Daoust, N. Rotaru, D. Biswas +9
The coherence of hole spin qubits in germanium planar heterostructures is limited by the hyperfine coupling to the nuclear spin bath due to 29Si and 73Ge isotopes. Thus, removing t…
Waveguide-Coupled Mid-Infrared GeSn Membrane Photodetectors on Silicon-on-Insulator
Cédric Lemieux-Leduc, Mahmoud R. M. Atalla, Simone Assali +5
Silicon photonics has thrived in telecommunications over recent decades, and its extension to the mid-infrared range has the potential to unlock valuable opportunities for sensing,…
Hole Spin in Direct Bandgap Germanium-Tin Quantum Dot
Nicolas Rotaru, Patrick Del Vecchio, Oussama Moutanabbir
Germanium (Ge) has emerged as a contender for scalable solid-state spin qubits. This interest stems from the numerous attractive properties of hole spin in Ge low-dimensional syste…
Heavy Hole vs. Light Hole Spin Qubits: A Strain-Driven Study of SiGe/Ge and GeSn/Ge
Kelvin Dsouza, Patrick Del Vecchio, Nicolas Rotaru +2
This work investigates and compares the impact of strain on heavy hole (HH) spin qubits in SiGe/Ge and light hole (LH) spin qubits in GeSn/Ge heterostructures, focusing on energy s…
Nuclear Spin-Depleted, Isotopically Enriched 70Ge/28Si70Ge Quantum Wells
O. Moutanabbir, S. Assali, A. Attiaoui +6
The p-symmetry of the hole wavefunction is associated with a weaker hyperfine interaction as compared to electrons, thus making hole spin qubits attractive candidates to implement…
