III-Nitride alloys such as InN, GaN, and AlN dominate the optoelectronics industry with applications in light emitting devices (LED), laser diodes (LD), and power electronics and constitute one of the most important semiconducting materials nowadays. In this project the bulk thermodynamics of these alloys are investigated.
