Mechanisms of charge carriers nonequilibrium in transport processes in bipolar semiconductors

Current Applied Physics, 2016
Abstract The interplay between physical origins of the nonequilibrium and their influence on the linear steady state transport processes in bipolar semiconductors are under investigation. Particular attention is paid to the influence of the energy nonequilibrium on the generation-recombination processes under various conditions.

Transport of Non-Equilibrium Charge Carriers in Bipolar Semiconductor Materials

2006 25th International Conference on Microelectronics, 2006
In this work we present results concerning the fundamental equations of charge carrier transport in semiconductor structures. We discuss the modeling of the recombination term in the charge transport equations for each type of carriers that respects the charge conservation law. It was obtained that under stationary conditions and equal generation rates

A unified analytical model for charge transport in Heterojunction Bipolar Transistors

Solid-State Electronics, 2004
Abstract A unified analytical charge transport model of HBTs, which is applicable for a wide variety of emitter-base (e–b) structures of HBTs, viz. abrupt or graded heterojunctions and p–n junctions displaced into wider or narrower band gap material is proposed.

Bipolar Charge Transport in Fullerene Molecules in a Bilayer and Blend of Polyfluorene Copolymer and Fullerene

Advanced Materials, 2010
Efficient polymer solar cells typically contain the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), which promotes dissociation of excited states and enhances charge transpo ...

Bipolar charge transport analysis in high voltage stressed dielectrics

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1985, 1985
Modern pulse power machines commonly use deionized water in intermediate energy storage capacitors. Recent work has shown that charge injection phenomena can play an important role in determining the limits of performance of the dielectric [1]. For unipolar conduction, this anomalous behavior was shown to be due to injected charge that increases the ...

A model for bipolar charge transport, trapping and recombination in degassed crosslinked polyethene

Journal of Physics D: Applied Physics, 1994
Measurements of the space charge density across the width of a plane parallel sample of degassed crosslinked polyethene (XLPE) have been made recently. Repeated at intervals throughout a period of applied high voltage, these measurements provide data on the dynamics of charge injection and space charge development in the sample under the influence of a

Intramolecular charge transfer in bipolar molecules for electron and hole transporting materials

Physical Chemistry Chemical Physics, 2004
The excited state relaxation of 6-(9H-carbazole)hexyl-9,10,10-trioxo-9H-3-thioxanthenecarboxyl (CHTT) molecules containing electron donating and electron accepting groups was investigated in solutions by means of picosecond pump–probe absorption spectroscopy.

Effect of gaseous void on bipolar charge transport in layered polymer film

Journal of Physics D: Applied Physics, 2014
This paper describes a hybrid algorithm to study the effect of a gaseous void on bipolar charge transport in layered polymer film. This hybrid algorithm uses a source distribution technique based on an axisymmetric boundary integral equation method to solve the Poisson equation and a fourth order Runge–Kutta (RK4) method with an upwind scheme for time ...
