Abstract

The temperature and doping dependence of the tunneling spectrum of Bi2.1Sr1.9CaCu2Ox single crystals was obtained by using a low-temperature scanning tunneling microscope. Above Tc, for x≤8.27, the tunneling density of states shows a clear gap-like feature with a larger gap value than the superconducting one, while for x>8.27, it shows the feature expected from the conventional superconducting fluctuation (SCF). We determined the SCF component in the static susceptibility (χ). By subtracting the effect of the SCF from χ, we confirmed that the two pseudogap phase boundaries determined by the tunneling and χ coincide with each other.
