topological monolayers

There has been growing interest in the study of 2D topological quantum states. Recent experiments established monolayer WTe₂ as a 2D topological insulator, which also becomes a superconductor via gating. This has triggered a lot of excitement in studying a wide range of topological properties of monolayer WTe₂ and its cousins, such as MoTe₂. We will report our investigations on the quantum transport behavior of monolayer WTe₂ and MoTe₂ in nano-fabricated devices, in the direction of searching for topological superconductivity.
