Reversible pressure-induced structure changes in turbostratic BN-C solid solutions.
The results obtained by Rietveld analysis and numerical modeling of B-C-N layered clusters with various types of lattice defects explain the evolution of diffraction patterns of turbostratic graphite-like BN-C solid solutions which are experimentally observed at room temperature at pressures up to 30 GPa. Above 20 GPa a reversible diffusionless transformation of the initial turbostratic structure takes place, giving a high-pressure phase formed by close-packed buckled layers having a diamond-like structure.
