In-plane quasi-particle tunneling into Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}

PDF Version Also Available for Download.

Description

Planar tunneling spectroscopy is performed into the a-b plane of the high-temperature superconductor Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}. The tunneling spectra exhibit a zero-bias conductance peak (ZBCP). Preliminary studies as a function of temperature, crystallographic orientation, magnetic field magnitude and direction confirm the ZBCP is an Andreev bound state (ABS) at zero energy. Below 5K, a depletion in the density of states at zero energy is observed.
