Enhancing charge stability of Ge quantum well heterostructures via SiGe layer composition engineering
Ding-Ming Huang, Jun-Hang Liu, Han Gao +10
Composition modulation is a powerful technique for designing materials with tailored properties, fueling the development of advanced semiconductor devices. In this work, we have im…
Microwave Response of the Superconducting Diode Effect in Proximitized Bilayer Graphene Interferometers
Shili Yan, Rubén Seoane Souto, Yi Luo +7
Microwave irradiation has emerged as a promising means to tune the superconducting diode effect (SDE) in Josephson junction devices. Previous experimental studies have mainly focus…
Single-Crystalline Al/Ge Heterostructure with an Atomically Sharp Commensurate Interface
Jian-Huan Wang, Ding-Ming Huang, Han Gao +3
A key challenge in developing Al/Ge heterostructures for quantum applications is Al-Ge interdiffusion. This process is facilitated by grain boundaries in polycrystalline films, whi…
Spin splitting, Kondo correlation and singlet-doublet quantum phase transition in a superconductor-coupled InSb nanosheet quantum dot
Xingjun Wu, Ji-Yin Wang, Haitian Su +6
We realize a superconductor-coupled quantum dot (QD) in an InSb nanosheet, a 2D platform promising for studies of topological superconductivity. The device consists of a supercondu…
Supercurrent and multiple Andreev reflections in Ge hut nanowire Josephson Junctions
Han Gao, Jian-Huan Wang, Ji-Yin Wang +2
We report an experimental study of induced superconductivity in Ge hut nanowire Josephson junctions. The Ge hut nanowires are grown on prepatterned SiGe ridges via molecular beam e…
