Comparison of electron transporting layer in white OLED with a double emissive layer structure

Displays, 2012
Abstract White organic light-emitting devices consisting of a non-doped ultrathin orange emissive layer (EML) and a doped blue EML were fabricated. The effect of varying electron transporting layers on device performance was studied, while 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline, 4,7-diphenyl-1,10-phenanthroline, tris(8-hydroxy-quinolinato ...

On Electronic and Transport “Anomalies” in Layered Oxides

Journal of Superconductivity, 1999
We briefly discuss some electronic and transport "anomalies" observed in superconducting perovskites. In particular we consider: (i) the complex electronic (and crystallographic) phase diagram, (ii) the symmetry of the gap with a special emphasis on the evidence for s-wave component in various experiments, and (iii) non-Fermi-liquid transport in ...

Electronic recombinations and ionic transport in BPSG layers

Microelectronic Engineering, 2001
Abstract Thermally stimulated luminescence (TSL) and current (TSC) measurements above room temperature were performed on 1150 nm borophosphosilicate glass films obtained by sub-atmospheric chemical vapour deposition. Several concentrations of B and P ions were considered, in the range 2–5% and 4–9% in weight, respectively.

Electronic Transport Properties of ZnSe Layers on GaAs

MRS Proceedings, 1989
AbstractThe electronic transport properties of ZnSe layers grown by MBE on GaAs sub- strates are studied by small-signal ac admittance, dc current-voltage, and Hall effect measurements. This work is supplemented by a study of TEM and x-ray rocking curve data.

Electron Transport Layers in Perovskite Solar Cells

2021
In recent years, the power conversion efficiency of perovskite solar cells has increased substantially, reaching today's values of above 25%. This has also placed an increased focus on device stability, which still limits commercial use. Electron transport layers (ETL) are critical for both factors in perovskite solar cells and have received much ...

Monte Carlo study of electron transport in silicon inversion layers

Physical Review B, 1993
Electron transport in Si inversion layers at 300 K is studied using a self-consistent Monte Carlo solution of the Boltzmann transport equation coupled to the two-dimensional Poisson equation and the one-dimensional Schr\"odinger equation. Physical elements included in the model are (1) nonparabolicity effects to treat quantization in the inversion ...

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.

MOS Electron Transport Layers as Solar Cells

Journal of Nanosciences Research & Reports
Ultrasonic spray pyrolysis technique emerges as the simplest and most feasible. For thin- film preparation, this method is superior to other techniques because it produces relatively homogeneous compositions, allows easy control of film thickness, and yields a fine and porous microstructure. The size of the nanoparticle prepared from various techniques

Nanostructured electron transport layers in PSC

2019
In perovskite solar cells (PSC), high photovoltaic performance is governed by the extent of electron mobility. For electron transport material (ETM), TiO2 films have been widely accepted. Having similar electron band structure and physical properties to TiO2, ZnO is a viable low- temperature alternative, especially as it can be easily solution ...

Fabrication of SnO2 layer as electron transport layers for perovskite solar cells

2023
A SnO2 has attracted more attention as electron transport layer (ETL) for perovskite solar cells (PSCs) because it has diverse advantages, e.g., wide bandgap energy, excellent optical and chemical stability, high transparency, high electron mobility, and easy preparation.
