Mechanism of electron transport and bipolar resistive switching in lead oxide thin films

open access: yesAIP Advances, 2018
In this paper, we report a model that interprets the mechanism of bipolar resistive switching in thin metal oxide layers as a purely electronic process.

An experimental study of polymer electrolyte fuel cell operation at sub-freezing temperatures [PDF]

open access: yes, 2013
The ability of polymer electrolyte fuel cells (PEFCs) to startup at subfreezing temperatures is governed by whether it is able to overcome the freezing point (0°C) before product ice prevents the electrochemical reactions. In this work, we experimentally

Atomistic and mesoscopic modelling of electric charge evolution in polymers [PDF]

open access: yes, 2001
We address some of the issues relating to charge transport in polymer based devices. We examine the effects of variable chain length on both intramolecular and intermolecular bipolar charge transport in polydiacetylene (PDA) and poly(para ...

Bipolar spin blockade and coherent state superpositions in a triple quantum dot

open access: yes, 2013
Spin qubits based on interacting spins in double quantum dots have been successfully demonstrated. Readout of the qubit state involves a conversion of spin to charge information, universally achieved by taking advantage of a spin blockade phenomenon ...

Mesoscopic study of bipolar charge transport in polymer-based devices

open access: yesSynthetic Metals, 2001
AbstractWe present generalised Monte-Carlo calculations of bipolar charge carrier transport in polydiacetylene (PDA) to assess effects of some key factors on the properties of polymer-based light-emitting diodes (PLEDs). Our mesoscopic model includes specific realisations of the polymer network and examines the effect of polymer structural order on ...

Research on Surface Charge Migration Characteristics of Two-Layered Polymer Film Based on Bipolar Charge Transport Model

open access: yesEnergies
A cable accessory is a critical component in constructing high-voltage direct current (HVDC) power grids, and it is typically composed of multiple materials. Due to the discontinuity of the insulation medium, it is prone to failure. This study focuses on
