Abstract: Considering the dependence of the gap on the exchange energy in ferromagnetic d-wave superconductor, we use an extended Blonder-Tinkham-Klapwijk approach to investigate the shot noise in semiconductor/ferromagnetic d-wave superconductor junction by solving the Bogoliubov-de Gennes（BdG） equation. It is shown that the exchange energy h0 in the ferromagnetic d-wave superconductor may induce a split of the shot noise double-peak at zero-bias and the energy gap peak, and the interval between the two split peaks is equal to 2h0; furthermore, with the increasing exchange energy h0, the shot noise and the ratio of shot noise power to average current are restrained.
