Spatial dependencies of the pair potential and the local density of statesnear the surfaces of $d_{x^{2}-y^{2}}$-wave superconductors are studiedtheoretically. The calculation is based on the t-J model within a mean-fieldtheory with Gutzwiller approximation. Various types of surface geometries areconsidered. Similar to our result in the extended Hubbard model, it is foundthat the formation of zero-energy states strongly depends on the surfacegeometry. In addition to this feature, the zero-energy states give peaksplitting for the (110) surfaces when the super-exchange interaction $J$ islarge. This is due to the induced s-wave component near the surface. Thepresent result explains the microscopic origin of the spontaneous time-reversal symmetry breaking at the surfaces of high-$T_{c}$ superconductors.Comment: 8 pages, 3 figures, to appear in Journal of the Physical Society of  Japan Vol.67 No.
