Description
With a critical temperature twice that of niobium, Nb$_3$Sn is the most promising alternative material for the future of Superconducting Radio-Frequency (SRF) technology, steadily advancing towards practical applications. In this collaborative study, we developed a framework to synthesize, characterize and compare substrate preparations based on oxide composition and surface roughness, aiming to understand tin nucleation mechanisms and design optimal substrate surfaces for high quality Nb$_3$Sn films. Our results show that anodized Nb substrates provide more nucleation sites and offer insight into the chemical composition of the oxide layer before and after heating to nucleation temperatures.
