Abstract

Abstract Exploring 2D van der Waals (vdW) materials is of great importance to the various optoelectronics‐based applications. Herein, mono‐ and few‐layer nanoflakes of a novel 2D vdW MgTeMoO6 are prepared by facile mechanical exfoliation method. These nanoflakes remain highly stable when being exposed in air even for 1 month, which is unique compared to most of 2D materials. Temperature‐dependent Raman spectroscopy reveals that 2D MgTeMoO6 nanosheets exhibit stronger interlayer interaction than that of graphene. In situ, angle‐resolved polarized Raman spectroscopy investigation show evidences for the anisotropic photo–phonon interactions. Notably, strong in‐plane anisotropy for the second harmonic generation (SHG) independent of layer number is observed for 2D MgTeMoO6, making 2D MgTeMoO6 promising in polarization‐sensitive optoelectronic applications.
