Though hexagonal boron nitride is generally regarded as the most stable boron nitride structure, the relative phase stabilities of boron nitride polymorphs are still under debate. Researchers led by the Japan Advanced Institute of Science and Technology used Monte Carlo simulations to calculate the relative phase stabilities of these polymorphs.
