In situ synchrotron studies of the structural properties of Y-Ba-Cu-O thin films during growth

Abstract
We report the first real time, in situ synchrotron x‐ray studies of Y‐Ba‐Cu‐O thin‐film growth on (100) SrTiO3 using a miniature, faced‐magnetron sputtering system. A combination of the substrate temperature and the deposition rate determines whether the film grows along the a, c, or multiple axes.
