The effect of temperature on the formation process structure of Ga0.2N0.8 semiconductor material using molecular dynamics simulation.
Main Article Content
Abstract
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.
