(TTT) 2I 3+δ compounds--superconducting fluctuations?
Abstract
We suggest that the high conductivity observed in non-stoichiometric (TTT) 2I 3+δ samples is a consequence of the suppression of 3D corrections by the incommensurate iodine chains which produce a random potential on the conducting TTT chains. As a result, the TTT chains can act as an array of independent 1D conductors for which it is known that superconducting fluctuations, suppressed in the 3D case, are strong and lead to high conductivity.
