Tóm tắt

This paper investigates the effect of temperature on the structural formation of Ga₀.₂N₀.₈ semiconductor materials. Temperature ranges from 300 K to 20 K were studied using molecular dynamics (MD) simulation. Results obtained after cooling showed the formation of several face-centered cubic (FCC), hexagonal close-packed (HCP), body-centered cubic (BCC), and amorphous (Amor) structures. These results provide a theoretical basis for future experimental studies and guide the application of Ga–N in low-temperature electronic devices.
