We present a method to analyze the results of first-principles based calculations of electronic currents including inelastic electron-phonon effects. This method allows us to determine the electronic and vibrational symmetries in play, and hence to obtain the so-called propensity rules for the studied systems. We show that only a few scattering states--namely those belonging to the most transmitting eigenchannels--need to be considered for a complete description of the electron transport. We…

Influence of vibrations on electron transport through nanoscale contacts
In this paper, we present a novel semi-analytical approach to calculate first-order electron–vibration (EV) coupling constants within the framework of density functional theory. It combines
Scattering theory approach to inelastic transport in nanoscale systems
We present a scattering-state description for the nonequilibrium multichannel charge transport in the presence of electron-vibration couplings. It is based on an expansion of scattering orders of
Inelastic effects in electron transport studied with wave packet propagation
A time-dependent approach is used to explore inelastic effects during electron transport through few-level systems. We study a tight-binding chain with one and two sites connected to vibrations. This
Simulation of inelastic electronic tunneling spectra of adsorbates from first principles.
The calculated spectra of carbon oxide and acetylene molecules adsorbed on Cu(100) surface have well reproduced their experimental counterparts and the performance of gradient-corrected density functional is compared with that of local density functional.
Nonequilibrium electronic structure of interacting single-molecule nanojunctions: vertex corrections and polarization effects for the electron-vibron coupling.
The effects of the double-exchange diagram and the diagram in which the vibron propagator is renormalized by one electron-hole bubble are considered, which find that it is indeed necessary to go beyond the SCBA in order to obtain correct results for a wide range of parameters.
Selection Rule of Inelastic Electron Tunneling Spectroscopy Probed by Isotope Substitution
We have investigated the inelastic process for alkanethiol self-assembled monolayers by using the isotope labeling and unambiguously determine the vibrational modes active in the inelastic electron
Elastic and inelastic electron transport in metal-molecule(s)-metal junctions
Abstract An overview of studies on elastic and inelastic electron transport properties of molecular junction devices is presented. The development of the experimental fabrication and characterization
Functionality in single-molecule devices: model calculations and applications of the inelastic electron tunneling signal in molecular junctions.
It is shown that the features in the inelastic electron tunneling spectra (IETS) of the molecular junctions are virtually independent of the nature of the molecule-lead contacts.
Effects of dephasing in molecular transport junctions using atomistic first principles
We report a theoretical investigation of dephasing effects to quantum transport properties of molecular junctions. The quantum transport analysis is done by density functional theory carried out
Mixed-valency signature in vibrational inelastic electron tunneling spectroscopy.
This analysis of IETS unambiguously reveals the paramagnetic nature of O2 on Ag(110), and the unforeseen consequence of the authors' calculations is that when adsorbed along the [001] direction, molecular O 2 on Ag (110) is a mixed-valent system.
