	abstract = {The structures formed by one-half and one monolayer (ML) of Pd evaporated onto Cu(100) at 300 K were studied by low energy electron diffraction (LEED), medium energy ion scattering (MEIS), thermal desorption spectroscopy (TDS), and embedded atom method (EAM) calculations. In the half monolayer case, the LEED I(E) curves are consistent with the established c(2 x 2) surface alloy model. The MEIS data, however, suggest that a fraction of the Pd (similar to 1/4) is in {\textquoteright}{\textquoteright}second layer{\textquoteright}{\textquoteright} sites, in agreement with previous LEIS, TDS and XPS forward scattering measurements. The EAM simulations support the formation of alloy islands, providing a mechanism for the covering of some Pd atoms. As the deposition proceeds, however, this island formation is indicated to occur preferentially over clean copper. In the one monolayer case, a p(2 x 2)-p4g LEED pattern is observed. Analysis of the I(E) curves suggests that this arises from (100) Pd packed above the c(2 x 2) alloy. EAM calculations confirm the stability of this model. Evidence from MEIS and TDS, however, shows that the one monolayer surface as prepared in this work is inhomogeneous. c(2 x 2) and Cu rich surface domains exist in addition to those having the p4g Pd/c(2 x 2)PdCu structure.},

	abstract = {A tensor LEED analysis of the Cu(110)-(2 x 3)-N surface structure supports. a reconstruction model in which the topmost layer can be described as a pseudo-(100)-c(2 x 2)-N overlayer, with metal corrugation of about 0.52 angstrom in the reconstructed layer. Each N atom is nearly coplanar with the local plane formed by the four neighboring Cu atoms. Of the four N atoms per unit mesh, three also bond to Cu atoms in the layer below and are therefore five-coordinate. Two of the three five-coordinate sites result from appreciable lateral displacements toward each other of both N atoms and Cu atoms below in the topmost Cu(110) layer. Average N-Cu bond lengths for the five-coordinate sites (1.87 angstrom) agree well with prediction, while the bond lengths for the four-coordinate sites (1.85 angstrom) appear somewhat long. These different N sites are discussed in relation to a recent STM study, and results from this LEED analysis are contrasted with those from the previous LEED study, which supported a [001]-missing row reconstruction of the surface.},
