Surface and Thin Film Phenomena

Computer simulations suggest that ultrathin metal wires should develop exotic, noncrystalline stable atomic structures once their diameter decreases below a critical size of the order of a few atomic spacings. The new structures, whose details depend upon the material and the wire thickness, may be dominated by icosah…

Electronic transport in materials is governed by a series of tensorial properties such as conductivity, Seebeck coefficient, and effective mass. These quantities are paramount to the understanding of materials in many fields from thermoelectrics to electronics and photovoltaics. Transport properties can be calculated…

We have investigated phase stability in the layered intercalation compound for x < 0.4 from first principles. By combining a lattice model description of the Li‐vacancy configurational degrees of freedom with first‐principles pseudopotential calculations, we have calculated the free energy of the material as a functio…

We have investigated the melting behavior of thin lead wires using molecular dynamics. We find that---in analogy with cluster melting---the melting temperature ${\mathit{T}}_{\mathit{m}}$(R) of a wire with radius R is lower than that of a bulk solid ${\mathit{T}}_{\mathit{m}}^{\mathit{b}}$ by ${\mathit{T}}_{\mathit{m}…

Atomic resolution high angle annular dark field imaging of suspended, single-layer graphene, onto which the metals Cr, Ti, Pd, Ni, Al, and Au atoms had been deposited, was carried out in an aberration-corrected scanning transmission electron microscope. In combination with electron energy loss spectroscopy, employed t…

Scanning tunneling microscopy and first-principles atomic orbital based calculations have been used to study ${\mathrm{TiO}}_{2}(110)1\ifmmode\times\else\texttimes\fi{}2.$ A structure is proposed that resolves the controversy surrounding the surface morphology. Our model is simple, in that it consists only of atoms in…

We combine scanning tunneling microscopy (STM) measurements with ab initio calculations to study the self-assembly of long chain alkanes and related alcohol and carboxylic acid molecules on graphite. For each system, we identify the optimum adsorption geometry and explain the energetic origin of the domain formation o…

Field confinement at the junction between a biased scanning probe microscope's tip and solid surface enables local probing of various bias-induced transformations, such as polarization switching, ionic motion, and electrochemical reactions. The nanoscale size of the biased region, smaller or comparable to that of feat…
