Normal state Nernst effect, semiconducting-like resistivity and diamagnetism of underdoped cuprates
preprintposted on 2006-04-04, 09:44 authored by A.S. Alexandrov
Semiconducting-like low-temperature in-plane resistivity indicates that there are no remnants of superconductivity above the resistive phase transition at T > Tc in underdoped cuprates. The model with the chemical potential pinned near the mobility edge inside the charge-transfer optical gap describes quantitatively the Nernst effect, thermopower, diamagnetism and the unusual low-temperature resistivity of underdoped cuprates as normal state phenomena above Tc.
