Comment: Essence of intrinsic tunneling: Distinguishing intrinsic features from artifacts [Phys.Rev.B 72 (2005) 094503]

Abstract

In a recent paper V.Zavaritsky has argued that interlayer ($c-$ axis) current-voltage characteristics of high temperature superconductors (HTSC) are Ohmic, and has claimed to disprove all findings of intrinsic tunnelling spectroscopy, as well as existence of the interlayer tunnelling and the intrinsic Josephson effect in HTSC, as such. In this comment I demonstrate, that the genuine interlayer current-voltage characteristics are strongly non-Ohmic, which undermines the basic postulate and the logical construction of the criticized paper.
