Borosilicate glass is a potential dopant source for producing shallow boron junctions by the use of proximity rapid thermal diffusion. Interest in this technique has increased recently due to its application to the manufacture of solar cells. A boros

Aligned cobalt nanowires, 1, 2, and 3 atoms wide, were grown on platinum (997) surfaces under UHV conditions and capped with five monolayers of gold. X-ray magnetic circular dichroism (XMCD) measurements were performed at the L2,3 edges of Co. Elemen

Reflectance anisotropy (RA) spectra of clean, dimerized Si and Ge (001) surfaces with (2×1), p(2×2), and c(4×2) surface unit cells and Sb covered Ge(001) with a (2×1) unit cell are calculated using a local orbital hybrid density functional theory

Chiral synthesis is an important route to biologically useful chemicals. Linear optical techniques like circular dichroism are too weak to detect chirality in monolayers of small molecules at surfaces, unless the surface area is very high and, in add

Hybrid DFT calculations of atomic structure, electronic band structure, and reflectance anisotropy (RA) are used to correlate atomic and electronic structures and optical transitions of eight structures for the $\mathrm{Si}(111)\text{\ensuremath{-}}(

We present a joint experimental-theoretical study of the reflectance anisotropy of clean and gold-covered Si(557), a vicinal surface of Si(111) upon which gold forms quasi-one-dimensional (1D) chains parallel to the steps. By means of first-principle

The molecules of life are chiral. Advanced materials for heterogeneous enantioselective catalysis and biomolecular sensing and recognition will need nanoscale chiral structures, and methods of characterizing them. Optical circular dichroism (CD) is t

Lead forms elongated islands when grown on vicinal Si(111) surfaces. Polarized infrared transmittance studies have shown a strong anisotropic optical response associated with antenna-like plasmonic resonances, whose spectral position in the region of

Measurements of the surface vibrational modes and optical response of Si(111)-(4 x 1)/(8 x 2)-In are compiled and a comparison to ab initio calculations performed within DFT-LDA formalism is given. Surface resonant Raman spectroscopy allows identifyi
