FIG. 3.

Strain vs film thickness for epitaxial on Nb (110). (●) Strain of a film measured during deposition. (◇) Strain observed for a number of samples after deposition and cooling, with error bars indicating the range of strain values measured along different RHEED azimuths.

FIG. 4.

(Color online) XRD pole figure for an epitaxial trilayer grown on -plane sapphire. Both Nb layers have a (110) surface orientation. This scan shows the off-axis ⟨110⟩ Bragg peaks. The four peaks connected by the dashed rectangle are approximately four times stronger than the others.
