Variable Temperature Scanning Tunneling Spectroscopy of Inhomogeneous High Temperature Superconductors

ORAL

Abstract

Scanning Tunneling Microscopy (STM) of the high temperature superconductor $Bi_2Sr_2CaCu_2O_{8+x}$ (Bi-2212) long ago revealed large gap variations on nanometer length scales. In this talk I will discuss new results from our temperature dependent STM studies of Bi-2201. In particular, I will focus on the effects of these variations on other observables, such as the states generated around single atom impurities, as well as on other measurement techniques, such as angle resolved photoemission (ARPES).
