Theory of Extrinsic and Intrinsic Tunnelling in Cuprate Superconductors
arXiv:1004.4429 · doi:10.1088/0953-8984/22/40/403202
Abstract
A theory capable of explaining intrinsic and extrinsic tunnelling conductance in underdoped cuprates has been devised that accounts for the existence of two energy scales, their temperature and doping dependencies. The asymmetry and inhomogeneity seen in extrinsic (normal metal - superconductor (NS)) tunnelling and the normal-state gapped intrinsic (SS) conductance is explained, as well as the superconducting gap and normal state pseudogap and the temperature dependence of the full gap.
