Pressure-induced isostructural phase transformation in γ-B28
Isostructural phase transformations (ISPhTs) so far were reported only for heavy elements and their compounds with complex electronic and/or magnetic structures. Studies of one of the lightest elemental material, high-pressure boron γ-B28, by means of in situ single-crystal x-ray diffraction and Ram...

| Summary: | Isostructural phase transformations (ISPhTs) so far were reported only for heavy elements and their compounds with complex electronic and/or magnetic structures. Studies of one of the lightest elemental material, high-pressure boron γ-B28, by means of in situ single-crystal x-ray diffraction and Raman spectroscopy reveal abrupt changes in the compressional behavior and Raman spectra at 40 GPa. Combined experimental and ab initio theoretical analysis of the structural and vibrational properties of γ-B28 suggests that the ISPhT under compression is due to the changes in the polarity of the covalent bonds between the boron atoms in the complex quasimolecular structure of γ-B28. |
