Atomic structure and dynamics of defects and grain boundaries in 2D Pd2Se3 monolayers

Abstract:

We study the atomic structure and dynamics of defects and grain boundaries in monolayer Pd2Se3 using annular dark field scanning transmission electron microscopy. The Pd2Se3 monolayers are reproducibly created by thermally induced phase transformation of few-layered PdSe2 films in an in situ heating holder in the TEM to promote Se loss. A variety of point vacancies, one-dimensional defects, grain boundaries (GBs), and defect ring complexes are directly observed in monolayer Pd2Se3, which show...
