We present a first-principles study of the GdRh2Si2(001) surface electronic structure. Two surfaces, Si- and Gd-terminated, are considered. The origin of the two-dimensional (2D) electronic states at both terminations is investigated by tracing the b

The electronic structure of the FeTi(110) surface has been calculated theoretically using the self-consistent film linearized augmented-plane-wave method. As a result, surface states both above and below the Fermi level have been found. Most of occup
