Abstract

It is proposed that the temperature dependence of the superconducting gap Δ(T) in high-Tc cuprates can be predicted just from the knowledge of Δ(0) and the critical temperature Tc, and, in particular, Δ(0)/Tc>4 implies that Δ(Tc)≠0, while Δ(0)/Tc≤4 corresponds to Δ(Tc)=0. A number of tunneling experiments appear to support the above proposition, and, furthermore, show reasonable quantitative agreement with a model based on the two-dimensional stripe hypothesis.
