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 ...

Towards Understanding the Ion Transport in Polyelectrolyte-Modified Nanopores with Bipolar Charges

ECS Meeting Abstracts, 2016
Fundamental understanding of ion transport is crucial for designing nanofluidic/nanopore devices. In particular, nanopores modified with synthetic or biological polyelectrolyte (PE) brushes have emerged as a potential tool for rectifying ionic current and characterizing individual biomolecules. Due to its asymmetric charge density distribution, bipolar

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 ...

Droplet-resolved transport and charge neutralization in bipolar electrosprays

Transport Phenomena
Abstract Electrohydrodynamic atomization (EHDA) enables precise control of droplet size but inherently produces highly charged droplets, limiting its applicability in charge-sensitive processes such as pulmonary drug delivery. Bipolar EHDA has emerged as a promising strategy for in-flight charge neutralization through the interaction ...

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 ...
