The high-Tc superconductor Bi2CaSr2Cu2O8 (Bi 2:1:2:2) exhibits a superstructure in the bulk which is manifested at the surface. Helium atom scattering (HAS) from the (001) Bi–O surface has revealed unusual features of the surface phonons, such as t

The spectral function of the electron–phonon interaction, determined by a tunneling experiment, is compared with a calculated phonon density of states. The agreement between them is considerable. For each peak in α 2 F , atomic displacements of th

The high-{ital T}{sub {ital c}} compound Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} exhibits an anisotropic superstructure. Helium atom scattering (HAS) has revealed unusual characteristics in the surface phonons of the Bi-O surface, namely occurrence of

We extend to crystals of the rutile structure our previous studies of the surface dynamics of ionic crystals within the framework of the shell model. These crystals have many interesting features due to their relatively open structure. Among the crys

We have treated the relaxation and the dynamics of the (110) surfaces of the cesium halogens CsCI, CsBr and CsI in the framework of shell models, in which the short range interactions are represented by Born-Mayer potentials. The relaxation in the su

We present a lattice-dynamical treatment of ${\mathrm{Nd}}_{2}$${\mathrm{CuO}}_{4}$ (T' structure) in the framework of a shell model that is based on short-range overlap and long-range Coulomb potentials, and includes ionic polarizabilities. We have

The authors discuss the relaxation, reconstruction and dynamics of both (001) surfaces of SrTiO3 (SrO and TiO2 surfaces) in the framework of shell models. The treatment of the SrO surface (surface I) on the basis of a bulk shell model leads to relaxa
