Dielectrics represent a new frontier for surface-enhanced Raman scattering. They can serve
as either a complement or an alternative to conventional, metal-based SERS, offering key …

Titanium dioxide photosensitization may be achieved in various ways, involving surface
modification with appropriate species. The photosensitization process requires a visible light …

The interaction of light with molecular conduction junctions is attracting growing interest as a
challenging experimental and theoretical problem on one hand, and because of its potential …

The electroluminescence of a polythiophene wire suspended between a metallic surface
and the tip of a scanning tunneling microscope is reported. Under positive sample voltage …

We present an expression for the lowest order nonzero contribution to the surface-enhanced
Raman spectrum obtained from a system of a molecule adsorbed on a semiconductor …

A new multiscale computational methodology was developed to effectively incorporate the
scattered electric field of a plasmonic nanoparticle into a quantum mechanical (QM) optical …

We present a brief pedagogical review of theoretical Green's function methods applicable to
open quantum systems out of equilibrium, in general, and single molecule junctions, in …

We report on a theoretical analysis and experimental verification of a mechanism for
photoconductance, the change in conductance upon illumination, in symmetric single …

Electron transport and optical properties of a single molecule in contact with conductive
materials have attracted considerable attention because of their scientific importance and …

We study the thermodynamic efficiency of a nanosized photoelectric device and show that at
maximum power output, the efficiency is bounded from above by a result closely related to …
