Piezoelectricity of Atomically Thin WSe2 via Laterally Excited Scanning Probe Microscopy

Ehsan Nasr Esfahani, Terrance Li, Bevin Huang +2

Lattices of odd-layered two-dimensional (2D) transition metal dichalcogenides (TMDs) such as WSe2 are non-centrosymmetric, and thus could possess linear piezoelectricity that is at…
