  • 本文研究了低温凝聚InSb膜相变过程中出现的时间效应和超导电性,获得了几个重要结果:(a)低温凝聚InSb膜从发生第一次电导跃变以后到第二次电导跃变之前,样品处于同一非晶金属态,并且具有相同的超导转变温度Tc;(b)Tc和退火温度Ta的关系十分类似于电导随Ta的变化关系;(c)随着第二次电导峰值后的电导下降,在某些特殊的相变区R(T)超导转变中,样品由完全的超导电性逐渐过渡到部分的超导电性;(d)相变过程中存在显著的时

     

    In this work, the time effects and superconductivity in the process of phase transition in InSb films condensed at low temperatures are studied. The following important experimental results are obtained: (a) Between occurrence of the first and the second conductance jump, the film samples are in the same amorphous metallic state, and have the same superconducting transition temperature Tc. (b) The relationship between Tc and annealing temperature ta is very similar to that between conductivit σ and Ta. (c) After the second jump, the conductance decreases, during the process of super conducting transition in certain transition zone R(T), the samples transform gradually from perfect to partially superconducting, (d) There are obvious time effects in the process of phase transition.
