Abstract
We investigate the superconducting properties of two-dimensional topological materials, in particular the quantum spin Hall system with on-site pairing. Accordingly, three types of edge states are found, which are topologically protected fermionic states at zero field, topologically protected Majorana states at finite Zeeman fields, and unpaired fermionic states without topological protection. Applications to transition metal dichalcogenides are also discussed.
