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…
Spin- and valley-polarized transport across line defects in monolayer MoS2
Artem Pulkin, Oleg V. Yazyev
We address the ballistic transmission of charge carriers across ordered line defects in monolayer transition metal dichalcogenides. Our study reveals the presence of a transport ga…
