Abstract

The pressure effects on the melting curve of indium are revisited based on the Force-Heat Equivalence Energy Density Principle approach up to 15 GPa. Our findings indicate a strong dependence of the melting temperature of indium metal on pressure. Our melting curve is in good agreement with recent two-phase picosecond acoustics measurements in combination with resistively heated diamond anvil cells up to pressure 15 GPa. In particular, we derive the initial melting slope of indium as

d T_{m} / d P \approx 51.31

K/GPa. And our melting curve of indium can be well-fitted by the Simon–Glatzel relation as

T_{m} = 429.7485 {(P / 4.4005 + 1)}^{1 / 1.8653}

重述金属铟在高压下的熔化曲线

基于力-热等效能量密度原理，重新研究了压力对铟熔解曲线的影响。我们的研究结果表明，金属铟的熔化温度对压力有很强的依赖性。我们的熔化曲线与最近的两相皮秒声学测量结果很好地吻合，结合电阻加热的金刚石砧细胞，压力高达15 GPa。特别地，我们得到铟的初始熔化斜率为dTm/dP≈51.31 K/GPa。用Simon-Glatzel关系式可以很好地拟合铟的熔化曲线：Tm=429.7485P/4.4005+11/1.8653。

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
