摘要：

We have studied the surfaces of discontinuous AgBr films epitaxially grown on LiF(001). The 3D AgBr islands are preferentially (111) oriented with [110] AgBr parallel-to [110] LiF and [110] AgBr parallel-to [110]BAR, LiF, respectively. By using the gold decoration technique a superstructure is revealed on the (111) top surfaces of the AgBr islands. The decorating gold nuclei are aligned along the <110> directions of the AgBr lattice. Optical diffraction exhibits sixfold symmetry of the superstructure with spacings of about 8.3 nm.
