Topological superconductivity in monolayer transition metal dichalcogenides

Theoretically, it has been known that breaking spin degeneracy and effectively realizing spinless fermions is a promising path to topological superconductors. Yet, topological superconductors are rare to date. Here we propose to realize spinless fermions by splitting the spin degeneracy in momentum space. Specifically, we identify monolayer hole-doped transition metal dichalcogenide (TMD)s as c...

Catalytic Activities of Transition Metal Phosphides for NO Dissociation and Reduction With CO

Transition metal phosphides are a group of compounds with interesting chemical/physical properties and potential applications in various fields, such as electronics, magnetism, photonics, catalysis, and so on1–4. In particular, metal phosphides (e.g. MoP, Ni2P, WP, Fe2P and Co2P) have been used as catalysts and extensively studied for hydrotreating reactions5–8. Among these phosphides, MoP, Ni2...

Metal-insulator transition in system with topological disorder

Metal-insulator transition in anisotropic disordered Anderson model with both topological and diagonal disorder is investigated numerically. For four sets of the model parameters we found the critical disorder and the critical exponent and prove that they do not depend on the transport direction. The system size independent critical conductance distribution Pc(g) is found for each critical poin...
