A comparative study has been made of iodine-intercalated Bi2Sr2Ca1Cu2Ox single crystal and 1 atm O2 annealed Bi2Sr2Ca1Cu1Ox single crystal using an AC susceptibility measurement, X-ray photoemission (XPS) and angle-resolved ultraviolet photoemission spectroscopy (ARUPS). The AC susceptibility measurement indicates that O2 doped samples studied have a T(c) of 84 K, whereas T(c) of the iodine-doped samples studied are 80 K. XPS Cu 2p core-level data establish that the hole concentration in the…
