Light-Hole Spin Qubits in Strained SiGe Lattice-Matched to Ge
Edmondo Valvo, Davide Costa, Patrick Del Vecchio +3
Strained germanium (-Ge) quantum wells on metamorphic SiGe buffers have enabled advanced hole-based spin qubit devices. Alternatively, unstrained Ge with lattice-match…
Tailoring Germanium Heterostructures for Quantum Devices with Machine Learning
Patrick Del Vecchio, Kevin Rossi, Giordano Scappucci +1
Germanium (Ge) quantum wells are emerging as versatile platforms for quantum devices, supporting high-quality spin qubits and integration with superconducting leads. These applicat…
Light-hole spin confined in germanium
Patrick Del Vecchio, Oussama Moutanabbir
The selective confinement of light holes (LHs) in a tensile-strained germanium (Ge) quantum well is studied by mapping the electronic structure of GeSn/Ge/GeSn$…
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…
Group IV Mid-Infrared Thermophotovoltaic Cells on Silicon
Gérard Daligou, Richard Soref, Anis Attiaoui +4
Compound semiconductors have been the predominant building blocks for the current mid-infrared thermophotovoltaic devices relevant to sub-2000 K heat conversion and power beaming.…
Radiative Carrier Lifetime in GeSn Mid-Infrared Emitters
Gérard Daligou, Anis Attiaoui, Simone Assali +2
GeSn semiconductors hold the premise for large-scale, monolithic mid-infrared photonics and optoelectronics. However, despite the successful demonstration of several Ge…
Light-Hole Gate-Defined Spin-Orbit Qubit
Patrick Del Vecchio, Oussama Moutanabbir
The selective confinement of light-holes (LHs) is demonstrated by introducing a low-dimensional system consisting of highly tensile-strained Ge quantum well enabling the design of…
