The discovery of graphene opens up the field of twodimensional (2D) materials such as h-BN , SiC , phosphorene , transitional metal dichalcogenides (TMDs) , and MXenes for both theoretical and experimental research. These materials have drawn considerable interest due to their novel physical and chemical properties compared to their three-dimensional (3D) bulk counterparts. Depending upon the crystal structure, most of the TMDs exhibit substantial mechanical strength with direct bandgap , higher carrier mobility , and strong spin-orbit coupling (SOC) . Unlike graphene and many other 2D materials, the in-plane asymmetry in TMDs provides them with extraordinary thermoelectric and optoelectronic properties . Particularly, chromium-based TMDs like CrS 2 and CrSe 2 show unique properties such as valley polarization in band structure , piezoelectric coupling, and phase-dependent intrinsic magnetic properties . For example, a previous report shows that CrS 2 nanosheet has the potential to use as negative electrodes in lithiumion batteries that could be promising for high-power energy storage . Similarly, strain engineering has been implemented in the CrS 2 to modify the electronic, mechanical anisotropy, and piezoelectric behavior . Moreover, reducing the dimension from 2D to 1D nanoribbon the electronic and magnetic behavior of CrS 2 changes significantly . In addition, the thermal and mechanical properties of Cr-based TMDs are promising materials when they are engineered in heterostructure form . Plus, the CrS 2 and CrSe 2 are two exceptional 2D valleytronic crystals with large valley spin splitting in the valence band .
