Cryogenic STM/STS observations of Pb-doped Bi2Sr2CuOy single crystals

Description

Cleaved ab-surfaces of Pb-doped Bi2Sr2CuOy (Bi2201) single crystals were probed by scanning tunneling microscopy/spectroscopy (STM/STS) at cryogenic temperatures below Tc. The obtained STS spectra clearly indicate a d-wave like gap structure superimposed on inverse V-shaped background, similar to the previous STS observations on pure Bi2201. Furthermore, we found that the gap value Δ was spatially non-uniform in a nanometer scale and ranged from 20 to 30 meV
