我们在硅衬底上制备出了厚度在原子尺度上可控、宏观尺度上均匀的铅薄膜。我们观察到了随着厚度一个原子层一个原子层增加时薄膜超导转变温度的振荡现象。我们证明,这种振荡行为是量子尺寸效应的结果。在这种薄膜中,电子德布罗意波的干涉行为类同于光的法布里-玻罗干涉,会? We fabricated lead films with controlled thickness and uniform macroscopically on the silicon substrate. We observed oscillations of the superconducting transition temperature of the film as the atomic layer of an atomic layer increases in thickness. We show that this oscillatory behavior is the result of the quantum size effect. In this film, the electronic de Broglie wave interference acts like the light of Fabry-Bolo interference,
