Title: Superconducting phonon spectroscopy using a low-temperature scanning tunneling microscope

Abstract

We report the first observation of phonon density of states effects in a superconductor using a low-temperature scanning tunneling microscope (STM). The phonon effects were observed using a STM spectroscopy method to measure dI/sub tunneling/ /dV vs V for the tunnel junction formed by the Au STM probe and a superconducting Pb sample.
