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…
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…
Atomically resolved electron reflectivity at a metal/semiconductor interface
Ding-Ming Huang, Jian-Huan Wang, Jie-Yin Zhang +3
An atomically flat interface is achieved between face-centered cubic Al and diamond lattice Ge via molecular beam epitaxy (MBE). Based on the measurements of scanning tunneling mic…
Scalable and Tunable In-Plane Ge/Si(001) Nanowires Grown by Molecular Beam Epitaxy
Jian-Huan Wang, Ming Ming, Ding-Ming Huang +7
Germanium nanostructures offer significant potential in developing advanced integrated circuit and disruptive quantum technologies, yet achieving both scalability and high carrier…
