Josephson energy of superconducting junctions: amorphous versus crystalline tunnel barriers
Wanting Zhang, Aldilene Saraiva-Souza, Félix Beaudoin +3
The Josephson energy is a key parameter governing the properties of transmon superconducting qubits. In Al/AlO/Al junctions, is set by electron tunneling through an…
Moiré Phonon Condensation in Magic-Angle Twisted Bilayer Graphene
Zhanghao Zhouyin, Jyun-jie Jiang, Xianghua Kong +1
Twisted bilayer graphene reconstructs from weak breathing corrugation to large common bending near the magic angle, but the origin of this collective crossover has remained unclear…
Cold source field-effect transistor with type-III band-aligned HfS/WTe heterostructure
Shujin Guo, Qing Shi, Deping Guo +4
The cold source field-effect transistor (CSFET) is promising for reducing power dissipation in integrated circuits by engineering the density of states at the injecting source. Exi…
Primitive-cell-resolved Crystallography for Moiré Bilayers from Imaging
Zhidan Li, Xianghua Kong
Accurate geometric decoding of moiré bilayers from imaging is essential for engineering quantum systems. Existing schemes, limited by identity or aligned assumptions requiring diag…
Electromechanical Switching and Momentum-Selective Transport in Geometry-Defined Blue Phosphorus Homojunctions
Zewen Wu, Min Zhou, Yanxia Xing +1
Developing intrinsic homojunctions without chemical heterogeneity remains a key challenge in future two - dimensional devices. Here, we report a geometry - defined metal--semicondu…
