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.

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 PCPDTBT‐PCBM Bulk‐Heterojunctions for Photovoltaic Applications

Advanced Functional Materials, 2008
AbstractAn experimental study of the transport properties of a low‐bandgap conjugated polymer giving high photovoltaic quantum efficiencies in the near infrared spectral region (Eg‐opt ∼ 1.35 eV) is presented. Using a organic thin film transistor geometry, we demonstrate a relatively high in‐plane hole mobility, up to 1.5 · × 10−2 cm2 V−1 s−1 and ...

Effect of injection barrier height on charge transport under bipolar injection

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2018
AbstractIn this paper, a numerical model describing the transient phenomena of electric charge in a dielectric because of a double injection at 2 electrodes is proposed. The mathematical model and the methods for its resolution are presented step by step.

Simulation of space charge behavior in LDPE with a modified of bipolar charge transport model

Proceedings of 2014 International Symposium on Electrical Insulating Materials, 2014
In this paper, an simply ion charge transport model is proposed, compared with bipolar charge transport model. It consists of ion generation by field assisted dissociation of impurities, transport, trapping and recombination in polymer. To simplify the model, it is assumed that only one type of impurity existing in polymer.

Charge transport properties of insulators revealed by surface potential decay experiment and bipolar charge transport model with genetic algorithm

IEEE Transactions on Dielectrics and Electrical Insulation, 2012
To evaluate spacecraft charging level and predict surface and internal electrostatic discharging (ESD) probability, it is important to know the charge transport properties of high insulation materials, such as epoxy resin/glass composition (FR4), Teflon and polyimide. In present work, the charge transport properties of the space insulators are revealed

Charge Transport Phenomena in Cryogenic SiGe Heterojunction Bipolar Transistors

Silicon-germanium heterojunction bipolar transistors (HBTs) are widely used for high-speed communications and radar systems owing to the their low-cost and competitive performance relative to III-V compound semiconductor devices. Due to the higher cost and lower yield of III-V high electron mobility transistors (HEMTs) based on InGaAs quantum wells ...

Charge Transport Regulation in Solution-Processed OLEDs by Indenocarbazole–Triazine Bipolar Host Copolymers

ACS Applied Materials & Interfaces
This work reports the synthesis of a series of bipolar host polymers, specifically PPPIC-co-PPDPT (9:1), PPPIC-co-PPDPT (8:2), and PPPIC-co-PPDPT (7:3), which incorporate a hole-transporting unit, 7,7-dimethyl-5-phenyl-2-(4-vinylphenyl)-5,7-dihydroindeno[2,1-b]carbazole (PPIC), and an electron-transporting unit, 2,4-diphenyl-6-(4-vinylphenoxy)-1,3,5 ...
