Ternary MgZ₂ N₄ (Z = Ge, Si) and Janus MgGeSiN₄ monolayers: high stability with distinctive electronic and magnetic properties.

ABSTRACT: The recent synthesis of two-dimensional (2D) MoSi₂N₄ and WSi₂N₄ crystals has given rise to a new class of 2D materials with distinctive properties and significant potential for advanced technologies. The transition metal (TM) elements can potentially be substituted with other elements from the periodic table, enabling the introduction of new members into this emerging 2D family. Building on this framework, we propose a new family of light-element-based 2D ternary compounds of MgZ₂N₄ (Z = Si, Ge) and their Janus derivative MgGeSiN₄ using first-principles density functional theory (DFT) calculations. All three monolayers are found to be dynamically, thermally, and mechanically stable. MgGe₂N₄ e
