摘要:
A method of preparing a superconducting thin film of niobium silicide using atomic layer deposition (ALD) where the superconducting critical temperature of the film is controllable by modulating the thickness of the thin film. The film is formed by exposing a substrate within an ALD reactor to alternating exposures of a niobium halide (NbQx) and a reducing precursor, for example, disilane (Si2H6) or silane (SiH4). A number of ALD cycles are performed to obtain the film thickness and establish the desired superconducting critical temperature between 0.4 K and 3.1 K.
