采用一种新的沉积方法制备了Nb/Ge细层状超导复合材料，并作为准二维超导模型系统进行了研究。在${T}_{c}$以下的平行临界场和${T}_{c}$以上的涨落电导率中，观察到超导性质的系统变化沿着具有二维到三维交叉行为。
Finely layered superconducting Nb/Ge composites have been fabricated with use of a novel deposition scheme and studied as model systems for quasi-two-dimensional superconductivity. Systematic variation of superconducting properties has been observed along with two- to three-dimensional crossover behavior in both the parallel critical fields below ${T}_{c}$ and the fluctuation conductivity above ${T}_{c}$.
