摘要：
We have investigated the superconductivity transition in a layered transition-metal dichalcogenide 2H-TaS2 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 tansition temperature within the specimen. © 1990.
