We have investigated doping dependence of Fermi surface, band dispersion, and magnetic structure in high-Tc cuprates by using Hartree-Fock calculation on a Cu 3d–O 2p tight-binding model. In the slightly electron-doped regime, electron pockets emerge around (π,0), which agrees with the photoemission study of Nd2-xCexCuO4. In the slightly hole-doped regime, hole pockets emerge around (π/2,π/2), which might explain the recent photoemission result of Ca2-xNaxCuO2Cl2.
