Аннотация
On the basis of the tunneling spectra of Bi2212, we report that there exist two kinds of pseudogaps; one with a characteristic energy comparable to the superconducting (SC) gap and another one that is 3 to 4 times larger. The smaller energy-scale pseudogap (SPG) develops progressively below temperature T*, which nearly scales with the SC gap amplitude D0, in addition to the larger energy-scale pseudogap (LPG). The SPG smoothly develops into the SC-state gap with no tendency to close at Tc.
