CDW Ordering in Stripe Phase of Underdoped Cuprates

TL;DR

This paper investigates charge-density-wave ordering in the stripe phase of underdoped cuprates, analyzing resistivity data to reveal 1D transport characteristics and the role of CDW in their electronic behavior.

Contribution

It provides new insights into the charge-density-wave ordering phenomena in underdoped cuprates and compares their transport properties with quasi-1D organic conductors.

Findings

Resistivity measurements indicate 1D transport properties in cuprates.

Step rise in resistivity at low temperatures is attributed to CDW ordering.

Phonon-electron interactions are significant at low temperatures.

Abstract

The in-plane resistivity and out-of-plane resistivity of non-superconducting RBCO (R = Y, Tm) and Fe-doped Bi2212 single crystals are discussed. The comparison of electrical transport properties of the cuprates and quasi-one dimensional (1D) (TMTSF)2PF6 organic conductor suggests that RBCO and Bi2212 exhibit 1D transport properties, and the step rise at low temperatures in the resistivities of the cuprates and quasi-1D organic conductor is due to charge-density-wave ordering. We discuss also phonon-electron interactions in cuprates at low temperatures.
