Conducting Polymers: Electrical Conductivity

2007
Abstract : While undoped polymers are insulators, doped conducting polymers have conductivities comparable to conventional metals and semiconductors despite their polymer chain structure. Models for the doping induced insulator-metal transition and the metallic conductivity of conducting polymers are introduced.

On the Perturb-and-Observe and Incremental Conductance MPPT Methods for PV Systems

IEEE Journal of Photovoltaics, 2013
This paper presents a detailed analysis of the two most well-known hill-climbing maximum power point tracking (MPPT) algorithms: the perturb-and-observe (P&O) and incremental conductance (INC).

Optimization of Conductance Change in Pr1–xCaxMnO3-Based Synaptic Devices for Neuromorphic Systems

IEEE Electron Device Letters, 2015
The optimization of conductance change behavior in synaptic devices based on analog resistive memory is studied for the use in neuromorphic systems. Resistive memory based on Pr1-xCaxMnO3 (PCMO) is applied to a neural network application (classification ...

Neuroid Conduction and the Evolution of Conducting Tissues

The Quarterly Review of Biology, 1970
Neuroid conduction, as here defined, refers to the propagation of electrical events in the membranes of non-nervous, nonmuscular cells. Examples from protistants, plants, and animals are described. In the dinoflagellate Noctiluca, propagated membrane depolarizations accompany the spread of the luminescent response, and local electrical changes are ...

Conductance of a Single Conducting Polyaniline Nanowire

Acta Physico-Chimica Sinica, 2005
The combination of template synthesis method of nanowire/nanotube and conductive atomic force microscopy (C-AFM) is an efficient way that can be used to probe the conductivity of single one-dimension nanomaterial and its array. This communication reports the conductivity of an electrochemically prepared single polyaniline(PANI) nanowire determined ...

Mesophyll conductance to CO2: current knowledge and future prospects.

Plant, Cell and Environment, 2008
During photosynthesis, CO2 moves from the atmosphere (C(a)) surrounding the leaf to the sub-stomatal internal cavities (C(i)) through stomata, and from there to the site of carboxylation inside the chloroplast stroma (C(c)) through the leaf mesophyll ...

Quantized Hall conductance, current carrying edge states, and the existence of extended states in a two-dimensional disordered potential

, 1982
When a conducting layer is placed in a strong perpendicular magnetic field, there exist current-carrying electron states which are localized within approximately a cyclotron radius of the sample boundary but are extended around the perimeter of the ...

Coupled Photosynthesis-Stomatal Conductance Model for Leaves of C4 Plants

, 1992
Leaf based models of net photosynthesis (An) and stomatal conductance (g) are often components of whole plant, canopy and regional models of net primary productivity and surface energy balance.
