By taking into account the interface scattering effect in a d-wave superconductor (S)/insulator layer (I)/d-wave superconductor (S) junction, the temperature dependence of the critical current and the current-phase relation are studied theoretically. It is found that both the barrier scattering and the roughness scattering at the interface always suppress the Andreev reflection and the current-phase relation is almost sinusoidal in the junction. The Josephson current strongly depends on the crystalline axis orientation of the d-wave superconductor in the junction. Some different phenomena appear depending on whether the crystal orientations of the superconductors on the two sides are the same or not, and this is mainly presented in the influence of the zero-energy states formation at the interface on the critical current which changes with temperature and phase.
