Abstract

Anisotropic behaviour of the A1g vibrational mode of MoS2 at the edges has been reported. Polarized Raman spectroscopy is used to identify edges, and decipher angles between them have been discussed. The aberrant appearance of the A1g mode at the edges has been attributed to breaking of back-scattering geometry. The direction-dependent intensity of the A1g mode is used to characterize the angle between edges, thus finding the chirality of the edges.
