Connecting the Nb-Sn phase diagram to electrical properties and process window. (a) Relevant adsorption-controlled growth regime (orange) of Nb-Sn phase diagram. Nb3Sn spans 17–25% Sn, and the desired Nb3Sn + liquid Sn field lies above 930 °C and 25% Sn. (b) Tc, ΔTc, vs the Sn flux of 60 nm thick Nb3Sn single layer thin films on Al2O3 substrates. Tc levels off above 1.0 Å/s Sn, corresponding to the adsorption-controlled growth window and the film composition reach 25% Sn.
