Abstract:
The quantitative effect on the thermal conductivity of Aluminum Nitride(AlN) regarding to Al mole fraction and temperature has not been reported computationally. Therefore, the goal of this study is to investigate the impact of Al mole fraction and temperature on the thermal conductivity of Al m N n numerically based on Boltzmann Transport equation by considering phonon scattering mechanisms. The theoretical thermal conductivity of Al m N n versus Al mole fraction and temperature is showed in this study. It is found that Point-defect and Umklapp scatterings are dominant scattering mechanisms for the thermal conductivity of Al m N n . The calculated thermal conductivity of Al m N n is verified through the comparison of experimental data versus Al mole fraction and temperature.
