Inhomogeneous electronic structures in heavily Pb-doped Bi2Sr2CaCu2Oy single crystals probed by low temperature STM/STS
Description
We have performed cryogenic scanning tunneling microscopy/spectroscopy (STM/STS) of heavily Pb-doped Bi2Sr2CaCu2Oy single crystals to investigate local electronic structures in the overdoped regime. The obtained STM/STS results at 4.3 K clearly showed local inhomogeneity of gap structure Δ (Δ=20-60 meV) in a scale of several nm, suggesting the coexistence of superconducting and pseudogap-like regions, even in the overdoped regime
