论文摘要
这项研究研究了磁场和压力下手性元素半导体（TE）的传输特性。与最近的理论和实验研究相反，静水压力的应用降低了TE的电阻率，而其温度依赖性仍为半导体，最高为4 GPA。较高压力的应用导致结构和半导体 - 金属过渡。所得的金属相高于4 GPA，在2 K处表现出超导性，以及明显的线性磁磁效应。另一方面，在环境压力下，我们确定了TE的锯齿状（10 $ \ bar {1} $ 0）上的金属表面状态。通过分析在高磁场中观察到的量子振荡，已经系统地研究了这些金属表面状态的性质。我们澄清说，明确的金属表面状态不仅存在于先前报道的化学蚀刻样品上，而且还存在于裂纹的样品上。
This study investigates the transport properties of a chiral elemental semiconductor tellurium (Te) under magnetic fields and pressure. Application of hydrostatic pressure reduces the resistivity of Te, while its temperature dependence remains semiconducting up to 4 GPa, contrary to recent theoretical and experimental studies. Application of higher pressure causes structural as well as semiconductor--metal transitions. The resulting metallic phase above 4 GPa exhibits superconductivity at 2 K along with a noticeable linear magnetoresistance effect. On the other hand, at ambient pressure, we identified metallic surface states on the as-cleaved (10$\bar{1}$0) surfaces of Te. The nature of these metallic surface states has been systematically studied by analyzing quantum oscillations observed in high magnetic fields. We clarify that a well-defined metallic surface state exists not only on chemically etched samples that were previously reported, but also on as-cleaved ones.
