Electronic traps in organic transport layers

physica status solidi (a), 2004
The knowledge about properties of electronic traps in organic semiconductors is one of the major keys for the understanding and optimization of charge transport in organic devices. In the present article the density of occupied states of the most prominent pristine small molecule systems and selected polymers are reported determined, by fractional ...

Electron-Transport Properties of Few-Layer Black Phosphorus

The Journal of Physical Chemistry Letters, 2015
We perform the first-principles computational study of the effect of number of stacking layers and stacking style of the few-layer black phosphorus (BPs) on the electronic properties, including transport gap, current-voltage (i-v) relation, and differential conductance.

Ion Motion in Conjugated Polyelectrolyte Electron Transporting Layers

Journal of the American Chemical Society, 2007
The time responses of polymer light-emitting diodes (PLEDs) incorporating conjugated polyelectrolyte electron transport layers (ETLs) are reported. Longer times are required with thicker ETL layers and with smaller applied voltages. These observations are consistent with a reduction of the electron injection barrier that depends on the ion motion in ...

ELECTRON–PHONON SCATTERING AND ELECTRONIC TRANSPORT IN LAYERED STRUCTURES

International Journal of Modern Physics B, 2000
The two-dimensional degenerate electron gas with electron–phonon scattering is analyzed. The normal-phase temperature dependence of the electrical resistivity and the thermo-electrical power are calculated, based on the electron–phonon scattering and other usual ones. Results are compared to those of earlier studies on three-dimensional phonon-limited

Electron Injection and Transport Mechanisms of an Electron Transport Layer in OLEDs

Journal of The Electrochemical Society, 2011
Electron injection and transport are key issues in the performance of organic light-emitting diodes (OLEDs). In this paper, an efficient n-doped electron transport layer (ETL) composed of 4,7-diphenyl-1,10-phenanthroline (Bphen) and lithium acetate (CH3COOLi) is demonstrated.

Electron Microscopy Investigation of Porous Transport Layer Coatings

ECS Meeting Abstracts, 2023
The flow of reactants and biproducts to and from the anode in polymer electrolyte membrane (PEM) water electrolyzers is dictated by the properties of the porous transport layer (PTL). The PTL is made of titanium (Ti) fibers or sintered particles to provide stable thermal and electronic conduction pathways at the high overpotentials and acid ...

Electron transport and electroluminescence in polymer layers

Russian Chemical Reviews, 1994
We shell discuss the transport of charge carriers (electron and holes) in disordered polymeric dielectric matrices and electroluminescence phenomena in transport layers of various structures, and also the injection of charges into transport layers through a boundary bearing a solid layer of a different type.

Electron transport in implant isolation GaAs layers

Microelectronics Reliability, 2003
Abstract We report results of ac electrical characterisation of diode structures with Hg electrodes and an implant isolation layer formed on a n + GaAs substrate. The C – f and G – f characteristics at varying bias voltage between 0 and 10 V at room temperature were examined.

Activated Electron‐Transport Layers for Infrared Quantum Dot Optoelectronics

Advanced Materials, 2018
AbstractPhotovoltaic (PV) materials such as perovskites and silicon are generally unabsorptive at wavelengths longer than 1100 nm, leaving a significant portion of the IR solar spectrum unharvested. Small‐bandgap colloidal quantum dots (CQDs) are a promising platform to offer tandem complementary IR PV solutions.
