  Andreev bound states at boundaries of d-wave superconductors are strongly
influenced by the boundary geometry itself. In this work, the zero-energy
spectral weight of the local quasiparticle density of states is presented for
the case of wedge-shaped boundaries with rounded corners. Generally, both
orientation of the d-wave and the specific local reflection properties of the
rounded wedges determine, whether Andreev bound states exist or not. For the
bisecting line of the wedge being parallel to the nodal direction of the d-wave
gap function, strong zero-energy Andreev bound states are expected at the round
part of the boundary.
