Molecular Thermoelectricity in EGaIn-Based Molecular Junctions
Accounts of Chemical Research, 2023ConspectusUnderstanding the thermoelectric effects that convert energy between heat and electricity on a molecular scale is of great interest to the nanoscience community. As electronic devices continue to be miniaturized to nanometer scales, thermoregulation on such devices becomes increasingly critical.

Coherently controlled molecular junctions
The Journal of Chemical Physics, 2012Within a generic model, we discuss the possibility of coherent control of charge fluxes in unbiased molecular junctions. The control is induced by resonances between the Rabi frequency due to a pumping laser field and internal characteristic frequencies of pre-designed molecular donor-bridge-acceptor complexes.

Spectroscopy of molecular junctions
Chemical Society Reviews, 2011In this tutorial review we present in detail recent studies in which molecular junctions were simultaneously probed by conductance measurements and optical spectroscopy methods such as electroluminescence (EL) and Raman scattering. The advantages of combining these experimental approaches to improve our understanding of charge transport through ...

Dissipation in molecular junctions
The Journal of Chemical Physics, 2008A recently developed theory that formulates the phenomena of inelastic transport and current-driven dynamics in molecular-scale electronics within a time-dependent scattering approach is extended to account for dissipation of the current-induced excitation through coupling to electrode phonons and electron-hole pairs. Our approach treats the electronic

All-Carbon Molecular Tunnel Junctions
Journal of the American Chemical Society, 2011This Article explores the idea of using nonmetallic contacts for molecular electronics. Metal-free, all-carbon molecular electronic junctions were fabricated by orienting a layer of organic molecules between two carbon conductors with high yield (>90%) and good reproducibility (rsd of current density at 0.5 V

Electromigrated molecular junctions
physica status solidi (b), 2006AbstractWe report on the fabrication and characterization of molecular junctions which are fabricated with electromigration and subsequent trapping of the molecule from solution. Transport measurements show molecule‐specific features (vibrational modes; gate coupling) and indicate the presence of a single molecule in the gap.

Thermoelectric efficiency of molecular junctions
Journal of Physics: Condensed Matter, 2016Focus of the review is on experimental set-ups and theoretical proposals aimed to enhance thermoelectric performances of molecular junctions. In addition to charge conductance, the thermoelectric parameter commonly measured in these systems is the thermopower, which is typically rather low.

Peltier cooling in molecular junctions
Nature Nanotechnology, 2017The study of thermoelectricity in molecular junctions is of fundamental interest for the development of various technologies including cooling (refrigeration) and heat-to-electricity conversion 1-4 . Recent experimental progress in probing the thermopower (Seebeck effect) of molecular junctions 5-9 has enabled studies of the relationship between ...

MOLECULAR ARCHITECTURE OF TIGHT JUNCTIONS
Annual Review of Physiology, 1998▪ Abstract The tight junction creates a regulated barrier in the paracellular pathway and, together with the actin-rich adherens junction, forms a functional unit called the apical junction complex. A growing number of tight junction–associated proteins have been identified, but functions are defined for only a few.

Bimetallic electrodes boost molecular junctions
Nature Materials, 2021Deposition of a one-atom-thick layer of Ag or Cu on Au electrodes proves to be an effective strategy to tune the band alignment and conductivity of molecular junctions.
