I have investigated the superconductivity transition in a layered transition-metal dichalcogenide 2H-Tas_2 by means of measuring electrical resistance down to 10 mK. We observed one which is highly sensitive to the current for the measurement of the electrical resistance. In addition the current-dependent- electrical resistance is clearly observed at 1.4 and 4.2 K respectively. This current-dependency is for the first time reported on this material. The physical origin is discussed in terms of the distribution of the superconductivity transition temperature within the specimen.

我通过测量低至 10 mK 的电阻研究了层状过渡金属二硫属化物 2H-Tas_2 中的超导转变。我们观察到一种对电流高度敏感的电阻测量装置。此外，分别在 1.4 K 和 4.2 K 处清晰地观察到与电流相关的电阻。这种电流依赖性是该材料首次报道。物理起源根据样品内超导转变温度的分布进行讨论。
