Rezumat | ||||||
Advanced technological process for high quality Nb film preparation of large area
(~600 mm2
) and constant nanoscale thickness is developed. Homogeneity and proper thickness of the Nb layer were proved by the target-holder movement during the DC sputtering.
The special protection cover Si-layer was used for a long-term stability of the superconducting properties of the prepared Nb films. The increase of superconducting critical temperature
(> 1.5 K for films with comparable thickness) in comparison with films prepared by conventional technique is reported. |
