利用电子隧穿方法研究了颗粒铝在金属-绝缘体转变过程中的超导性质。我们发现，随着样品电阻率的增加，超导能隙的边缘加宽，因为寿命的影响，直到扩大成为可比的差距。此时，超导电性消失。
By electron tunneling we have studied the superconducting properties of granular aluminum as one approaches the metal-insulator transition. We find that with increasing sample resistivity, the superconducting energy-gap edge broadens because of lifetime effects until that broadening becomes comparable to the gap. At this point, superconductivity disappears.
