WebAug 24, 2024 · Transition metal tellurides (TMTs) have attracted intense interest due to their intriguing physical properties arising from their diverse phase topologies. To date, a wide range of physical properties have been discovered for TMTs, including that they can act as topological insulators, semiconductors, Weyl semimetals, and superconductors. WebJan 13, 2024 · Based on the ab initio calculations, we show that MoTe2, in its low-temperature orthorhombic structure characterized by an x-ray diffraction study at 100 K, realizes 4 type-II Weyl points between ...

WebHerein, we report the realization of a broadband self-powered photodetector based on Type-II Weyl semimetal T d -MoTe 2 . The prototype metal-MoTe 2 -metal photodetector … WebNov 19, 2024 · We report the observation of a robust edge supercurrent in the Weyl superconductor MoTe2. In a magnetic field B, fluxoid quantization generates a periodic modulation of the edge condensate observable as a "fast-mode" oscillation of the critical current Ic versus B. Remarkably, the fast-mode frequency is distinct from the … german school chicago
