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…

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…
