Quantum spin Hall phase in GeSn heterostructures on silicon
B. M. Ferrari, F. Marcantonio, F. Murphy-Armando +2
Quantum phases of solid-state electron systems look poised to sustain exotic phenomena and a very rich spin physics. We propose a practical silicon-based architecture that spontane…
A high-mobility hole bilayer in a germanium double quantum well
A. Tosato, B. M. Ferrari, A. Sammak +4
We design, fabricate, and study a hole bilayer in a strained germanium double quantum well. Magnetotransport characterisation of double quantum well field-effect transistors as a f…
Electron-hole superfluidity in strained Si/Ge type II heterojunctions
Sara Conti, Samira Saberi Pouya, Andrea Perali +5
Excitons are promising candidates for generating superfluidity and Bose-Einstein Condensation (BEC) in solid state devices, but an enabling material platform with in-built bandstru…
Intersubband transition engineering in the conduction band of asymmetric coupled Ge/SiGe quantum wells
Luca Persichetti, Michele Montanari, Chiara Ciano +9
: n-type Ge/SiGe asymmetric-coupled quantum wells represent the building block of a variety of nanoscale quantum devices, including recently proposed designs for a silicon-based TH…
Room temperature operation of n-type Ge/SiGe terahertz quantum cascade lasers predicted by non-equilibrium Green's functions
T. Grange, D. Stark, G. Scalari +9
n-type Ge/SiGe terahertz quantum cascade laser are investigated using non-equilibrium Green's functions calculations. We compare the temperature dependence of the terahertz gain pr…
Low disordered, stable, and shallow germanium quantum wells: a playground for spin and hybrid quantum technology
A. Sammak, D. Sabbagh, N. W. Hendrickx +10
Buried-channel semiconductor heterostructures are an archetype material platform to fabricate gated semiconductor quantum devices. Sharp confinement potential is obtained by positi…
Gate-controlled quantum dots and superconductivity in planar germanium
N. W. Hendrickx, D. P. Franke, A. Sammak +9
Superconductors and semiconductors are crucial platforms in the field of quantum computing. They can be combined to hybrids, bringing together physical properties that enable the d…
