Keywords:nitride semiconductors, machine-learning potential, thermal conductivity

We describe the status of our studies on the effecs of singularity structures on various properties of nitride semiconductors, especially the effects of vacancies on the thermal conductivity of GaN crystal, using the machine-learning potentials that are expected to achieve low computational cost and high reliability simultaneously. We also discuss the future prospects of studies of singularity structures in nitride semiconductors using this method.
