Charge transport phenomena

Values of ft for charge transfer in proteins were determined experimentally in the range 1.0-1.4 A-1 [16]. In comparison, apparent /J values for DNA-mediated hole transfer were found in a wide range from /J < 0.1 up to 1.5 A-1 [11, 12]. For the alternative mechanistic description of DNA-mediated charge-transport phenomena over long distances which typically exhibit a very shallow distance depen-... 

The Poisson equation can also be used in modelling - charge transport phenomena in - semiconductors and -> conductive polymers [iv, v]. 

What is the origin of the charge transport phenomena and what do these experimental observations tell us about the material We show that the Mott-CFO model can answer these questions at least to first order, with the additional assumption that the density of localized band-tail states falls off exponentially away from the mobility edges. In this picture, the time-dependent charge transport is dominated by the statistical process associated with the progressive thermalization of electrons (or holes) into the band-tail states. We confine the discussion to electrons and assume that it can be generalized to holes trivially. 

Corrosion is here to stay. The wedding to materials science is implicitly reviewed in the first five figures. It is a clearly important complex materials science drawing on all the other disciplines. As the surface science of interphase mass and charge transport phenomena on solids continues to evolve then more clearly, defined new routes for product optimizations will be evident. 

Promising approach to charge transport phenomena in supramolecular systems is physicochemical and kinetical consideration of these reaction in terms of local properties of the media and reactants local permittivity, microviscosity, local concentrations, pH, pX, Ag, etc.). Relationships...
