Controlling the Quantum Spin Hall Edge States in Two-Dimensional Transition Metal Dichalcogenides

Oleg Yazyev, Artem Pulkin

Two-dimensional transition metal dichalcogenides (TMDs) of Mo and W in their 1T' crystalline phase host the quantum spin Hall (QSH) insulator phase. We address the electronic properties of the QSH edge states by means of first-principles calculations perfo ...

Manipulating Topological Domain Boundaries in the Single-Layer Quantum Spin Hall Insulator 1T '-WSe2

Oleg Yazyev, Yixing Chen, Michele Pizzochero, Artem Pulkin, Feng Wang

We report the creation and manipulation of structural phase boundaries in the single-layer quantum spin Hall insulator 1T'-WSe2 by means of scanning tunneling microscope tip pulses. We observe the formation of one-dimensional interfaces between topological ...

Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides

Oleg Yazyev, Artem Pulkin

Chalcogen vacancies are generally considered to be the most common point defects in transition metal dichalcogenide (TMD) semiconductors because of their low formation energy in vacuum and their frequent observation in transmission electron microscopy stud ...
