The discovery of 2D layered MoSi2N4 and WSi2N4 without knowing their 3D parents by
chemical vapor deposition in 2020 has stimulated extensive studies of 2D MA2Z4 system …

The stability and electronic properties of the hydrogenated Janus MSiGeZ 4 (M= Sc-Zn, Y–
Ag, Hf–Au; Z= N, P) monolayers are predicted by the first-principles calculations. There are …

Valleytronics has become an emerging field for both theoretical and experimental research.
Based on first-principles calculations, we demonstrate that the spin valley coupling and …

Full potential linearized augmented plan wave (FP-LAPW) method based on density
functional theory (DFT) is used to explore the optoelectronic, structural, thermo-electric and …

The recent discovery of synthetic two-dimensional materials has opened up a new paradigm
