Atomic-resolution Inelastic Electron Tunneling Spectroscopy studies of doping dependence of electron-boson interaction in Bi-2212

ORAL

Abstract

Inelastic Electron Tunneling Spectroscopy(IETS) has been one of the most powerful tool to probe collective modes in the solids. We use the recently developed \textit{STM-based Atomic-resolution Inelastic Electron Tunneling Spectroscopy(IETS)} technique to study the doping dependence of the electron-boson interactions(EBI) in Bi-2212 high-Tc cuprates. According to our results, the distribution of the bosonic mode energy($\Omega$) does not change as doping level changes, while the gap distribution changes greatly. Also $\Omega$-maps show nano-scale disorder. We will discuss the possible origin of this doping independent EBI.
