Scanning tunneling

I built one of the first low-temperature scanning tunneling microscopes, and used it to make tunneling measurements of the energy gaps of the high Tc cuprate superconductors, including some of the first tunneling measurements of the gap in polycrystalline and single crystal YBa2Cu3O7-δ.
