利用集成有金属薄膜电极的金刚石对顶砧,对微米氧化锌样品进行了原位高压电导率测量.结果表明,在9.19GPa时样品电导率达到最小值,在9.19—11.22GPa时样品电导率急剧增大,说明此时样品从纤锌矿结构向岩盐矿结构转变直至完全相变,11.22GPa为相变点.通过测量不同条件下高温退火处理的样品电导率,明显看到氧空位对电导率的影响. In-situ high-pressure conductivity measurement of ZnO samples with diamond anvil with integrated metal thin film electrode showed that the conductivity of samples reached the minimum at 9.19 GPa and sharp at 9.19-11.22 GPa Increase, indicating that the samples at this time from the wurtzite structure to the rock salt structure until the complete phase transition, 11.22GPa phase transition point by measuring the conductivity of samples annealed under different conditions, it is obvious oxygen vacancies on the conductivity Impact.
