Modeling Study of the Dip/Hump Feature in Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ Tunneling Spectroscopy

P. Romano, L. Ozyuzer, Z. Yusof +2

The tunneling spectra of high temperature superconductors on Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ (Bi-2212) reproducibly show a high bias structure in the form of a dip-hump at voltages h…
