Charging of Molecules during Transport

Nano Letters, 2005
The 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 in Eumelanin [PDF]

Melanins are a class of bio-macromolecules that are found throughout the biosphere. They fulfill various functions in human beings, which makes them a long studied substance in medicine and biology. Furthermore they possess a set of rare and special physico-chemical properties which include featureless broad band absorption in the UV-Vis spectrum and ...

Charge transport in nanoscale junctions

Journal of Physics: Condensed Matter, 2008
Understanding 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.

Charge Transport in Polypyrrole Nanotubes

Journal of Nanoscience and Nanotechnology, 2015
True 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, 1993
The 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 ...

Decoupling charge and heat transport

Science, 2017
Solid-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.

Transport of charged macromolecules across a biological charged membrane

Computer Programs in Biomedicine, 1985
The glomerular capillary wall of the kidney behaves as an electronegatively charged structure consisting of three layers, the lamina densa and the two laminae rarae, which are differently charged. Thus, a three layer model is proposed to analyse the transport of charged macromolecules across this wall.

Kinetics of Charges in Waveguides. Charge Transport

2019
The main aim in this chapter is to link the transport parameters with the temperature and nanowaveguide dimensions . This is achieved by formulating the problem in such a way as to include the Fermi–Dirac distribution function (FDF) as initial or boundary condition.

Charge Transport in Organic Semiconductors

2011
Modern optoelectronic devices, such as light-emitting diodes, field-effect transistors and organic solar cells require well controlled motion of charges for their efficient operation. The understanding of the processes that determine charge transport is therefore of paramount importance for designing materials with improved structure-property ...

Charge transport in magnetrons

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1987
The current conduction processes in a magnetron sputtering diode have been the subject of discussion since the origination of the device. Several techniques have been used to study these conduction processes. Langmuir probe measurements of electron temperature, density, and plasma potential show clear evidence of a positive space-charge sheath.
