Charge transport in nanoscale junctions
Journal of Physics: Condensed Matter, 2008Understanding the fundamentals of nanoscale charge transfer is pivotal for designing future nano-electronic devices. Such devices could be based on individual or groups of molecular bridges, nanotubes, nanoparticles, biomolecules and other 'active' components, mimicking wire, diode and transistor functions.

Long-Range DNA Charge Transport
The Journal of Organic Chemistry, 2003The stack of base pairs within double helical DNA has been shown to mediate charge transport reactions. Charge transport through DNA can result in chemistry at a distance, yielding oxidative DNA damage at a site remote from the bound oxidant. Since DNA charge transport chemistry depends on coupling within the stacked base pair array, this chemistry is ...

Vibration‐Assisted Charge Transport through Positively Charged Dimer Junctions
Angewandte Chemie International Edition, 2022AbstractIntermolecular charge transport plays a vital role in the fields of electronics, as well as biochemical systems. Here, we design supramolecular dimer junctions and investigate the effects of charge state and energy level alignment on charge transport under nanoconfinement.

Charge transport in desolvated DNA
The Journal of Chemical Physics, 2013The conductivity of DNA in molecular junctions is often probed experimentally under dry conditions, but it is unclear how much of the solvent remains attached to the DNA and how this impacts its structure, electronic states, and conductivity. Classical MD simulations show that DNA is unstable if the solvent is removed completely, while a micro-hydrated

Charging of Molecules during Transport
Nano Letters, 2005The possibility that a single molecule can acquire charge during steady-state transport is an open issue. We report first-principles calculations in a range of configurations of certain molecules and conclude the following. When a molecule is strongly coupled to the electrodes, charging is not sustainable.

Charge transport through molecular switches
Journal of Physics: Condensed Matter, 2010We review the fascinating research on charge transport through switchable molecules. In the past decade, detailed investigations have been performed on a great variety of molecular switches, including mechanically interlocked switches (rotaxanes and catenanes), redox-active molecules and photochromic switches (e.g. azobenzenes and diarylethenes).

Charge Transport in Polypyrrole Nanotubes
Journal of Nanoscience and Nanotechnology, 2015True metallic conductivity in conjugated polymers has been major challenge for the last few years. Heeger and co-workers have reported metallic conductivity in bulk polyaniline film, but the problem of metallic transport in their nanophase still remains unexplored.

Applications of acoustic charge transport
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1993The emerging technology of acoustic charge transport (ACT), which has enabled the implementation of powerful signal processors capable of handling high-speed RF and microwave signals in their natural analog domain, is reviewed. The development of ACT technology has led to the implementation of fully programmable analog signal processors capable of ...

Space Charge and Charge Transport in Polypropylene
2005 12th International Symposium on Electrets, 2006Space charge distributions in various polypropylene (PP) films were measured with the PEA method. Specimens were 100 /spl mu/m-thick films of homo-PP and PP-copolymers including -3 wt% ethylene which were polymerized using metallocene or Ziegler catalysts.

Decoupling charge and heat transport
Science, 2017Solid-State Physics In metals, electrons carry both charge and heat. As a consequence, electrical conductivity and the electronic contribution to the thermal conductivity are typically proportional to each other. Lee et al.
