    Abstract
  • The in-situ synchrotron radiation diffraction of gallium oxide under high pressure has been studied in the range of 0～42.5 GPa with diamond anvil cell (DAC), using methanol-ethanol-water (16∶3∶1) mixture as transmission medium. We have found that under room temperature, the monoclinic gallium oxide turns into a rhombohedral one under 13.3 GPa. After the phase changs, the Ga ions are only at the centers of the octahedrons instead of their original locations which are at both the centers of the octahedrons and the tetrahedrons. When the pressure goes back to ambient pressure, the sample turns back to monoclinic structure.
