Webtype-II Weyl semimetal, different from high pressure-induced superconductivity in the 1T’ phase WTe. 2 44-47 and superconductivity in the epitaxial WTe 2 thin film on a sapphire substrate48. The achievement of superconductivity in the 10 nm-thick sample implies a long superconducting coherence length along c axis in WTe 2. Based on the measured Webspectrum is gapless in semimetals. In Weyl semimet-als (WSM) every crossing point splits into two Weyl nodes with opposite chiralities due to the time rever-sal or inversion symmetries breaking. The projections of two Weyl nodes on the surface Brillouin zone are con-nected by a Fermi arc, which represents the topologically protected surface ...

Observation of non-trivial superconductivity on surface of type II Weyl …
WebAug 2, 2024 · MoTe 2 is a Weyl semimetal, which exhibits unique non-saturating magnetoresistance and strongly reinforced superconductivity under pressure. Here, we demonstrate that a novel mesoscopic superconductivity at ambient pressure arises on the surface of MoTe 2 with a critical temperature up to 5 K significantly exceeding the bulk Tc … WebMay 1, 2024 · Currently, γ–molybdenum ditelluride (γ-MoTe 2, where γ refers to the orthorhombic semimetallic phase) is the only Weyl semimetal that is known to be a superconductor ( 10, 11 ); at ambient pressure, its critical temperature Tc is 100 mK ( 12 ). Here, we report evidence for an edge supercurrent in this material. WebWeyl Semimetals, Fermi Arcs and Chiral Anomalies by Shuang Jia et al.
