Factors Affecting Formation of ‘in Situ’ and 110 K Phase Sputtered Bi-Based Superconducting Thin Fil ensure proper mixing and thus enhance the formation of 110 K phase. The melting point of the Bi-based materials seems to depend on the ambient gas, composition and the degree of prior chemical reaction. Thus the films deposited at substrate temperatures above 450° C melts in oxygen at ~890° C in ox

In-Situ Growth of Superconducting Films of Bi-Sr-Ca-Cu-O Using Magnetron Sputterings have a smaller energy barrier to overcome in forming a crystal structure. There is a narrow temperature window for growth of the superconducting phase; at lower temperatures the films tend to be semiconducting, due probably to lack of sufficient thermal energy to crystallize a well-ordered phase.
