What is the thermal conductivity of gallium nitride (GaN)?
For non-metallic crystalline materials including gallium nitride (GaN), heat is conducted mostly through lattice vibrations (phonons). Therefore, the thermal conductivity can be reduced by anything that affects phonon physics, which includes disloions and other extended defects, intrinsic point defects such as vacancies and antisites, and extrinsic defects (impurities).
