Research output: Contribution to journalArticlepeer-review


Planar tunneling spectroscopy is performed into the a-b plane of the high-temperature superconductor Bi2Sr2CaCu2O8. 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
