First principles coupled cluster theory of the electronic spectrum of the transition metal dichalcogenides
Artem Pulkin, Garnet Kin-Lic Chan
The electronic properties of two-dimensional transition metal dichalcogenides (2D TMDs) have attracted much attention during the last decade. We show how a diagrammatic ab initio c…
Controlling the quantum spin Hall edge states in two-dimensional transition metal dichalcogenides
Artem Pulkin, Oleg V. Yazyev
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 prope…
Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides with experiment and theory
Sara Barja, Sivan Refaely-Abramson, Bruno Schuler +17
Chalcogen vacancies are considered to be the most abundant point defects in two-dimensional (2D) transition-metal dichalcogenide (TMD) semiconductors, and predicted to result in de…
Observation of Topologically Protected States at Crystalline Phase Boundaries in Single-layer WSe2
Miguel M. Ugeda, Artem Pulkin, Shujie Tang +12
Transition metal dichalcogenide (TMD) materials are unique in the wide variety of structural and electronic phases they exhibit in the two-dimensional (2D) single-layer limit. Here…
