Implication

Molecular dynamics simulations investigate the impact of growth temperature on interfacial conductance in GaN/AlN heterostructures, suggesting improvements for thermal management.

Key Points

The study aims to understand how growth temperature affects the quality and thermal conductance of GaN films.
Conducted molecular dynamics simulations of GaN films at growth temperatures ranging from 500 to 1700 K.
Analyzed phonon density of states and spectral heat flux to assess heat transfer characteristics.
Compared interfacial thermal conductance of GaN/AlN heterostructures under various growth conditions.
Surface roughness of GaN films decreases as growth temperature increases.
Crystallinity improves and dislocation density reduces with higher temperatures.
Interfacial thermal conductance reaches a peak of 535 MW/(m2 K) at 1000 K before declining.
