Abstract

We report angle-resolved photoemission spectroscopy (ARPES) results from Bi2Sr2CaCu2O8+δ (2212) single-crystal thin films grown with atomic layer-by-layer molecular beam epitaxy (ALL-MBE). This was made possible by adapting the top-post cleaving technique to thin films of 2212. We have observed clear photoemission features from these films that disperse through the Fermi level. We have observed the superconducting energy gap with ARPES in thin films. Both the magnitude of the gap as well as its anisotropy are consistent with the results from bulk crystals. Furthermore, we observe the pile-up and dip in spectral weight associated with the gap. These results open possibilities for future research using thin-film samples in this materials system that take advantage of the ability to grow metastable materials with ALL-MBE.
