Mid-Infrared Detectors and Imagers Integrating All-Group IV Nanowires
Lu Luo, Mahmoud RM Atalla, Simone Assali +3
Cost-effective mid-wave infrared (MWIR) optoelectronic devices are of utmost importance to a plethora of applications such as night vision, thermal sensing, autonomous vehicles, fr…
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…
Atomic fluctuations lifting the energy degeneracy in Si/SiGe quantum dots
Brian Paquelet Wuetz, Merritt P. Losert, Sebastian Koelling +16
Electron spins in Si/SiGe quantum wells suffer from nearly degenerate conduction band valleys, which compete with the spin degree of freedom in the formation of qubits. Despite att…
In-plane selective area InSb-Al nanowire quantum networks
Roy L. M. Op het Veld, Di Xu, Vanessa Schaller +19
Strong spin-orbit semiconductor nanowires coupled to a superconductor are predicted to host Majorana zero modes. Exchange (braiding) operations of Majorana modes form the logical g…

Hao Zhang, Michiel W. A. de Moor, Jouri D. S. Bommer +19
We report electron transport studies on InSb-Al hybrid semiconductor-superconductor nanowire devices. Tunnelling spectroscopy is used to measure the evolution of subgap states whil…
Probing embedded topological modes in bulk-like GeTe-SbTe heterostructures
Hisao Nakamura, Johannes Hofmann, Nobuki Inoue +5
The interface between topological and normal insulators hosts metallic states that appear due to the change in band topology. While these topological states at a surface, i.e., a t…
Hard superconducting gap and diffusion-induced superconductors in Ge-Si nanowires
Joost Ridderbos, Matthias Brauns, Jie Shen +8
We show a hard induced superconducting gap in a Ge-Si nanowire Josephson transistor up to in-plane magnetic fields of mT, an important step towards creating and detecting Maj…
Selective-area chemical beam epitaxy of in-plane InAs one-dimensional channels grown on InP(001), InP(111)B, and InP(110) surfaces
