Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0035] Such as Figure 1-6 As shown, the polystyrene colloidal sphere and niobium film composite heterostructure superconducting material of the present invention includes a substrate, a niobium film and a polystyrene hexagonal array film, the niobium film is located on the substrate, and the A polystyrene hexagonal array film covers the niobium film;
[0036] The polystyrene hexagonal array film includes a plurality of polystyrene colloidal microspheres, and each polystyrene colloidal microsphere is closely arranged as a hexagonal array in a single layer.
[0037] Preferably, the substrate is a high resistance silicon substrate.
[0038] Preferably, the thickness of the niobium film is 70nm-200nm.
[0039] Preferably, the polystyrene colloidal microspheres have a diameter of 100nm-2000nm.
[0040] The preparation method of polystyrene coll...
