摘要

Abstract

We used nonlinear laser scanning optical microscopy to study atomically thin transition metal dichalcogenides (TMDs) and revealed

with unprecedented resolution

the orientational distribution of armchair directions and their degree of organization in the two-dimensional (2D) crystal lattice. In particular

we carried out polarization-resolved second-harmonic generation (PSHG) imaging for monolayer WS

and obtained

with high-precision

the orientation of the main crystallographic axis (armchair orientation) for each individual 120 × 120 nm

pixel of the 2D crystal area. Such nanoscale resolution was realized by fitting the experimental PSHG images

obtained with sub-micron precision

to a new generalized theoretical model that accounts for the nonlinear optical properties of TMDs. This enabled us to distinguish between different crystallographic domains

locate boundaries and reveal fine structure. As a consequence

we can calculate the mean orientational average of armchair a

ngle distributions in specific regions of interest and define the corresponding standard deviation as a figure-of-merit for the 2D crystal quality.
