Abstract

In order to clarify the tunneling spectroscopy in hole-doped high-Tc cuprates, we study the strongly correlated electron systems with surface using the 2D Hubbard model with fluctuation exchange (FLEX) approximation from the side of weak coupling theory. We have found that (i) LDOS near the (1, 1, 0) surface has a zero energy peak, and (ii) LDOS is asymmetric, reflecting the asymmetry of band structure and electron correlation in the hole-doped high-Tc cuprates.
