[[abstract]]By use of the slave-boson mean-field approach, we have studied the electron-doped t-t'-t''-J model in the antiferromagnetic (AF) state. It is found that at low doping the Fermi surface (FS) pockets appear around (+/-pi,0) and (0,+/-pi), and upon increased doping the other ones will form around (+/-pi/2,+/-pi/2). The evolution of the FS with doping as well as the calculated spectral weight are consistent with the experimental results.[[fileno]]2010128010006[[department]]物理
