Gate-defined quantum point contacts in a germanium quantum well
Han Gao, Zhen-Zhen Kong, Po Zhang +6
We report an experimental study of quantum point contacts defined in a high-quality strained germanium quantum well with layered electric gates. At zero magnetic field, we observe…

Ubiquitous missing first Shapiro step in Al-InSb nanosheet Josephson junctions
Xingjun Wu, Haitian Su, Chuanchang Zeng +6
The absence of odd-order Shapiro steps is a predicted signature of topological superconductors. Experimentally, the missing first-order Shapiro step has been reported in both putat…

Microwave-assisted unidirectional superconductivity in Al-InAs nanowire-Al junctions under magnetic fields
Haitian Su, Ji-Yin Wang, Han Gao +10
Under certain symmetry-breaking conditions, a superconducting system exhibits asymmetric critical currents, dubbed the ``superconducting diode effect". Recently, systems with the i…
