Thin films of the ceramic superconductor Ba(Pb1-xBix)O3 are of                  considerable interest both for their unusual superconducting and                electronic properties, and for their potential uses in superconducting          electronic devices.  While high quality single crystals of this                 material can be produced by ceramic processing techniques, it has               proven more difficult to make high quality films. Thin film samples are         currently being made (in Japan) by RF sputtering from a single                  composite target.  In this project,  an ultrahigh vacuum                        multiple-target sputter deposition system is being used to fabricate            thin films with much tighter control over the deposition process.  By           studying the interrelation between the deposition parameters and the            resulting film characteristics,  it should be possible to synthesize            thin films with properties nearly identical to the best single crystal          samples.  Such high quality films can then be used to study the origins         of the unusually high superconducting critical temperature (Tc = 13K)           in this low carrier density (n 1021/cm3) material.  In addition, the            potential uses of this material in superconducting electronics, and             especially as a microwave detector, are being investigated.
