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.
