Ferroelectricity in [111]-oriented epitaxially strained SrTiO from first principles
Sebastian E. Reyes-Lillo, Karin M. Rabe, Jeffrey B. Neaton
We use first principles density functional theory calculations to investigate the effect of biaxial strain in the low-temperature structural and ferroelectric properties of [111]-o…
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…
Large spin-orbit splitting of deep in-gap defect states of engineered sulfur vacancies in monolayer WS2
Bruno Schuler, Diana Y. Qiu, Sivan Refaely-Abramson +10
Structural defects in 2D materials offer an effective way to engineer new material functionalities beyond conventional doping in semiconductors. Specifically, deep in-gap defect st…
Bright sub-20 nm cathodoluminescent nanoprobes for multicolor electron microscopy
Maxim B. Prigozhin, Peter C. Maurer, Alexandra M. Courtis +18
Electron microscopy (EM) has been instrumental in our understanding of biological systems ranging from subcellular structures to complex organisms. Although EM reveals cellular mor…
Defect-induced modification of low-lying excitons and valley selectivity in monolayer transition metal dichalcogenides
Sivan Refaely-Abramson, Diana Y. Qiu, Steven G. Louie +1
We study the effect of point-defect chalcogen vacancies on the optical properties of monolayer transition metal dichalcogenides using ab initio GW and Bethe-Salpeter equation calcu…
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…
