Two-Dimensional MoSiN Family: Progress and Perspectives Form Theory.

Recently, a new two-dimensional (2D) layered MoSiN has been successfully synthesized by chemical vapor deposition without knowing the 3D counterparts [ 2020, 369, 670-674]. The unique septuple-atomic-layer structure and diverse composition of MoSiN have drawn tremendous interest in studying 2D MAZ systems based on the MoSiN structure. As an emerging family of 2D materials, MAZ materials exhibit a wide range of properties and excellent tunability, making them highly promising for various applications. Herein, we summarize recent significant progress in property characterization of the MAZ family. The electronic, magnetic, thermal transport, and superconducting properties, including their tunability through strain engineering and elemental substitution, are presented and elaborated in detail. Further perspectives and new opportunities of the emerging MAZ family are presented at the end of this Perspective.
