Recently, a new derivative of TMDs, the so-called Janus TMD (JTMD) has drawn considerable interest due to their unique physical and chemical properties from the conventional TMDs because of an out-of-plane structural asymmetry. A single layer JTMD, MoSSe, was successfully fabricated in the laboratory by fully replacing the top Se layer of MoSe 2 TMD and inserting the S layer by using the chemical vaporization deposition (CVD) technique . Further, several JTMDs have been studied theoretically , which are mostly semiconductors with an energy bandgap between 1.36 to 1.97 eV exhibiting strong optical absorption at the visible region . Particularly, the Janus chromium dichalcogenide monolayer (CrSSe) has broad optical absorption and low carrier recombination suitable for the photocatalytic system . In addition, it shows better performance in photocatalytic reactions, water molecule absorptions, utilization of sunlight, charge separation and transport, and surface chemical reactions . Similarly, 1T-phase of CrSSe JTMD possesses intrinsic 2D ferromagnetic behavior with large spin-polarization and Curie temperature higher than the room temperature .
