Molecular dynamics simulations reveal phase transitions in GaN alloys, indicating opportunities for advanced semiconductor designs.

The aim is to explore how composition and temperature affect the structural properties and phase transitions of Ga1-xNx alloys.
Performed molecular dynamics simulations on Ga1-xNx compounds with varying compositions (x = 0.2 to 0.8) and temperatures (300 K to 4 K).
Analyzed changes in bonding characteristics and structural phases as system size increased from 5,324 to 27,436 atoms.
Investigated the amorphous-to-crystalline phase transition and binding energy variations under different cooling conditions.
Ga–N bond length remains constant at 2.05 Å across various temperatures and doping levels.
Amorphous-to-crystalline phase transition occurs around 250 K, affecting structural characteristics.
Higher doping concentrations increase total energy while cooling decreases total binding energy and enhances structural smoothness.
