Rebuttal to "Comment by V.M. Krasnov on 'Counterintuitive consequence of heating in strongly-driven intrinsic junctions of Bi2Sr2CaCu2O8+d Mesas' "

TL;DR

This paper discusses how heating affects conductance peaks in intrinsic Josephson junctions of Bi2Sr2CaCu2O8+{eta}, showing that sharper peaks are due to extrinsic heating effects rather than intrinsic superconducting properties.

Contribution

It provides a reinterpretation of tunneling spectroscopy data, emphasizing the role of heating in shaping conductance features in high-temperature superconductor junctions.

Findings

Increased dissipation causes peak sharpening and loss of dip/hump features.

Sharp conductance peaks are extrinsic and heating-induced, not intrinsic.

Results align with previous studies on pristine Bi2212 and tunneling spectroscopy data.

Abstract

In our article [1], we found that with increasing dissipation there is a clear, systematic shift and sharpening of the conductance peak along with the disappearance of the higher-bias dip/hump features (DHF), for a stack of intrinsic Josephson junctions (IJJs) of intercalated Bi2Sr2CaCu2O8+{\delta} (Bi2212). Our work agrees with Zhu et al [2] on unintercalated, pristine Bi2212, as both studies show the same systematic changes with dissipation. The broader peaks found with reduced dissipation [1,2] are consistent with broad peaks in the density-of-states (DOS) found among scanning tunneling spectroscopy [3] (STS), mechanical contact tunneling [4] (MCT) and inferred from angle (momentum) resolved photoemission spectroscopy [5] (ARPES); results that could not be ignored. Thus, sharp peaks are extrinsic and cannot correspond to the superconducting DOS. We suggested that the commonality of the sharp peaks in our conductance data, which is demonstrably shown to be heating-dominated, and the peaks of previous intrinsic tunneling spectroscopy (ITS) data implies that these ITS reports might need reinterpretation.
