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 ...

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 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 ...

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 ...

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.

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 ...

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

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 ...
