Surface Enhancement of Superconductivity in Tin
arXiv:cond-mat/0504277 · doi:10.1103/PhysRevB.72.174510
Abstract
The possibility of surface enhancement of superconductivity is examined experimentally. It is shown that single crystal tin samples with cold-worked surfaces represent a superconductor with a surface-enhanced order parameter (or negative surface extrapolation length b), whose magnitude can be controlled.
