摘要
An equilibrium thermodynamic analysis of the Gibbs free energy in a non-hydrostatic stress field is applied to the formation of boron nitride thin films. The theory predicts a specific sequence of microstructures from non-oriented hexagonal boron nitride, through oriented hexagonal boron nitride and finally cubic boron nitride. It also predicts a threshold stress for cubic boron nitride formation. These predictions are in agreement with experimental observations reported here and made by others. The synthesis of cubic boron nitride in a new helicon wave plasma source is demonstrated. The operating parameters which produce the cubic phase are determined.
