説明

Abstract The high-pressure phase transitions and Raman phonon behaviors of LiGaO 2 were investigated by high-pressure Raman spectroscopy and first-principle calculations. The β -LiGaO 2 was evidenced to undergo irreversible phase transitions to Raman silent γ -LiGaO 2 at ∼14 GPa, and the high-pressure phase transition from α - to δ -phase was found to be kinetically sluggish at room temperature. In addition, mode-Gruneisen parameters, bulk modulus, and pressure dependence of Raman phonon frequencies LiGaO 2 were also determined.
