Giant critical current peak induced by pressure in kagome superconductor RbVSb
Lingfei Wang, Wenyan Wang, Tsz Fung Poon +11
Superconductivity can coexist or compete with other orders such as magnetism or density waves. Optimizing superconductivity requires identifying competing orders that may disrupt C…
Point-contact Andreev reflection spectroscopy of layered superconductors with device-integrated diamond anvil cells
Che-hsuan Ku, Omargeldi Atanov, King Yau Yip +9
Superconductors that can be mechanically exfoliated are an interesting platform for exploring superconducting properties tuned by layer thickness. These layered superconductors are…
Superconducting critical temperature and dimensionality tuning of RbVSb via biaxial strain
Tsz Fung Poon, King Yau Yip, Ying Kit Tsui +10
Kagome metal AVSb (A=K, Rb, Cs) has emerged as an intriguing platform for exploring the interplay between superconductivity and other quantum states. Among the three compou…
Discovery of a new phase in thin flakes of KVSb under pressure
Zheyu Wang, Lingfei Wang, King Yau Yip +13
We report results of magnetotransport measurements on KVSb thin flakes under pressure. Our zero-field electrical resistance reveals an additional anomaly emerging under pre…
Quantum Phase Transition as a Promising Route to Enhance the Critical Current in Kagome Superconductor CsVSb
Wenyan Wang, Lingfei Wang, Xinyou Liu +8
Developing strategies to systematically increase the critical current, the threshold current below which the superconductivity exists, is an important goal of materials science. He…
