We have used atomic layer-by-layer oxide molecular beam epitaxy to grow epitaxial thin films of [Formula see text] with x up to 0.5, greatly exceeding the solubility limit of Ca in bulk systems ([Formula see text]). A comparison of the optical conductivity measured by spectroscopic ellipsometry to prior predictions from dynamical mean-field theory demonstrates that the hole concentration p is approximately equal to x. We find superconductivity with [Formula see text] of 15 to 20 K up to the highest doping levels and attribute the unu
