Temperature and doping dependent FT-STS studies of Bi-2201

ORAL

Abstract

We present Fourier transform scanning tunneling spectroscopy (FT-STS) results in superconducting Bi-2201. The data presented are drawn from samples at a variety of dopings, and from experiments both below and above the superconducting transition temperature T$_{c}$. A number of unexpected trends are revealed by this systematic study. We interpret the results in light of several theories and make comparisons to results from other crystal systems.
