The granularity of the high-Tc cuprates, though has been considered to be obnoxious for many applications, appeared to giving rise to the exotic incremental charging effects. This paper further demonstrates that it can also serve as an alternative for extracting the superconducting gap parameters of these materials. The results of 2Δ(0)/K B T c ≈6-8(YBCO) and ≈ 9-11(Tl-1223), though are consistent with those obtained by other methods, the Δ(T)′S, however, are not BCS-like.
