高压下SnO的电输运行为研究
he electrical transport behavior of SnO under high pressure
通过测量原位霍尔效应和电阻率随温度的变化，SnO在高压下的电输运性质得到了研究。霍尔效应的实验结果很好的展现了SnO在高压下的载流子输运行为，表明SnO在1.3GPa处经历了P型到N型的载流子转变，同时在2-3GPa处有一个潜在的相变发生。此外，电阻率随温度的变化证明SnO在5GPa处发生了由半导体到金属的相变。特别的是，根据实验得到的数据给出了一个示意图来说明SnO随温度和压力的变化。
By means of the accurate in situ Hall-effect measurements and the temperature dependence of electrical resistivity measurements, the electrical transport properties of SnO under high pressure are investigated. The results of Hall-effect measurements display the carrier transport behavior of SnO under pressure, which indicates that SnO undergoes a carrier-type inversion around 1.3 GPa and an underlying phase transition at 2-3 GPa. In addition, the temperature dependence of electrical resistivity shows that SnO undergoes a semiconductor-to-metal transition around 5 GPa. In particular, based on experimental results a sketch is drawn to account for the variation of SnO with temperature and pressure.
