Title: Photonics and spectroscopy in nanojunctions: a theoretical insight

Abstract

The progress of experimental techniques at the nanoscale in the last decade made optical measurements in current-carrying nanojunctions a reality, thus indicating the emergence of a new field of research coined optoelectronics. Optical spectroscopy of open nonequilibrium systems is a natural meeting point for (at least) two research areas: nonlinear optical spectroscopy and quantum transport, each with its own theoretical toolbox. We review recent progress in the field comparing theoretical treatments of optical response in nanojunctions as is accepted in nonlinear spectroscopy and quantum transport communities. A unified theoretical description of spectroscopy in nanojunctions is presented. Here, we argue that theoretical approaches of the quantum transport community (and in particular, the Green function based considerations) yield a convenient tool for optoelectronics when the radiation field is treated classically, and that differences between the toolboxes may become critical when studying the quantum radiation field in junctions.

  • Solid-state 1H magic-angle spinning (MAS) NMR was used to investigate local proton environments in anhydrous [UO 2(OH) 2] (α-UOH) and hydrated uranyl hydroxide [(UO 2) 4O(OH) 6·5H 2O (metaschoepite). For the metaschoepite material, proton resonances of the μ 2-OH hydroxyl and interlayer waters were resolved, with two-dimensional (2D) double-quantum (DQ) 1H– 1H NMR correlation experiments revealing strong dipolar interactions between these different proton species. The experimental NMR results were combined with first-principles CASTEP GIPAW (gauge including projector-augmented wave) chemical shift calculations to develop correlations between hydrogen-bond strength and observed 1H NMR chemical shifts. Furthermore, these NMR correlations allowed characterization ofmore » local hydrogen-bond environments in uranyl U 24 capsules and of changes in hydrogen bonding that occurred during thermal dehydration of metaschoepite.« less

  • By means of tight-binding quenched-molecular-dynamics simulations, we have investigated the adsorption of a Co impurity on the reconstructed Au(111)-(22{times}{radical}3) surface. The possible sites for nucleation on the Au inhomogeneous substrate have been identified and hierarchized in energy. Apart from the pure fcc and hcp sites on the homogeneous part of the substrate, the adatom experiences less pronounced minima in the pseudoternary sites on the sides of the discommensuration lines. Surprisingly, the stablest position is reached at the apparently low coordinated bridge site on top of the defect lines. We show that this can be understood from both relaxation and segregationmore » effects.« less
  • The eight unique Diels-Alder cycloadditions of butadiene to C{sub 70} are analyzed theoretically and compared with the well-established, two possible Diels-Alder cycloadditions of butadiene to C{sub 60}. Full geometry optimizations of reactants, adducts, and transition states are performed using the AMI semiempirical method followed by single-point ab initio energy calculations. The results show that the cycloaddition of butadiene to the C{sub 70} fullerene in the gas phase is slightly more reactive than that to C{sub 60}. However, in toluene solution calculations yield that the different solvent effects on C{sub 60} and C{sub 70} cause a significant decrease of the energymore » barrier in the C{sub 60} cycloaddition, thus predicting a larger reactivity for C{sub 60} as compared to the C{sub 70} fullerene. 36 refs., 2 figs., 3 tabs.« less
  • We performed ab initio quantum chemical studies for the development of intra and intermolecular interaction potentials for formic acid for use in molecular dynamics simulations of formic acid molecular crystal. The formic acid structures considered in the ab initio studies include both the cis and trans monomers which are the conformers that have been postulated as part of chains constituting liquid and crystal phases under extreme conditions. Although the cis to trans transformation is not energetically favored, the trans isomer was found as a component of stable gas-phase species. Our decomposition scheme for the interaction energy indicates that the hydrogenmore » bonded complexes are dominated by the Hartree-Fock forces while parallel clusters are stabilized by the electron correlation energy. The calculated three-body and higher interactions are found to be negligible, thus rationalizing the development of an atom-atom pair potential for formic acid based on high-level ab initio calculations of small formic acid clusters. Here we present an atom-atom pair potential that includes both intra- and inter-molecular degrees of freedom for formic acid. The newly developed pair potential is used to examine formic acid in the condensed phase via molecular dynamics simulations. The isothermal compression under hydrostatic pressure obtained from molecular dynamics simulations is in good agreement with experiment. Further, the calculated equilibrium melting temperature is found to be in good agreement with experiment.« less
