ABSTRACT

In conclusion, we have successfully prepared a new 2D van der Waals material, MnTeMoO6, by mechanical exfoliation. This material is very stable in air. The large in-plane anisotropy of phonon vibration modes is revealed by ARPRS measurements. The origin of anisotropy within its large surface is explained by structural analysis. The SHG responses of MnTeMoO6 flakes are odd/even layer-independent in a wide wavelength range (820–1200 nm). Our research presents a potential choice for delving into the interlayer coupling and fabricating novel inminiaturized photonic equipment.
