We present angular resolved photoemission spectroscopy measurements about the Fermi surface of a Bi2Sr2CaCu2Os+ (Bi2212) thin film. Dispersion curves in two directions are discussed. It is confirmed that the Fermi surface observed on the Bi2212 thin film fits the bulk Fermi surface.
In-situ superconducting thin films ofLi-doped Bi2Sr2CaCu208 have been prepared on MgO single-crystal substrates by a pulsed laser ablation technique. Among the different parameters studied, substrate temperature and oxygen pressure during the deposition have been found to be most important. Depositi
