Polyoxovanadate-modified SnO2 electron transport layer for perovskite photodetectors

open access: yesPolyoxometalates
SnO2 is widely used in perovskite photodetectors as an electron transport layer material. The matching of the energy levels of SnO2 and perovskite is important in carrier transport.

Coulomb oscillations in three-layer graphene nanostructures

open access: yes, 2008
We present transport measurements on a tunable three-layer graphene single electron transistor (SET). The device consists of an etched three-layer graphene flake with two narrow constrictions separating the island from source and drain contacts.

Electron transport in Si/SiGe modulation-doped heterostructures using Monte Carlo simulation

open access: yes, 2003
The electron transport in the two-dimensional gas formed in tensile-strained Si1-xGex/Si/Si1-xGex heterostructures is investigated using Monte Carlo simulation. At first the electron mobility is studied in ungated modulation doped structures.

Temperature dependent metallic conductance above the mobility edge of a silicon inversion layer [PDF]

open access: yes, 1981
The temperature dependence of the conductance of an n-type inversion layer on a (100) silicon surface has been examined between 1.4K and 4.2K at electron densities at which the Fermi level is close above the mobility edge of the lowest sub-band.

Suppression of energetic electron transport in flares by double layers

open access: yes, 2012
During flares and coronal mass ejections, energetic electrons from coronal sources typically have very long lifetimes compared to the transit times across the systems, suggesting confinement in the source region.

Self-consistent Coulomb picture of an electron-electron bilayer system

open access: yes, 2006
In this work we implement the self-consistent Thomas-Fermi approach and a local conductivity model to an electron-electron bilayer system. The presence of an incompressible strip, originating from screening calculations at the top (or bottom) layer is ...

Dipole-field-assisted charge extraction in metal-perovskite-metal back-contact solar cells [PDF]

open access: yes, 2017
Hybrid organic-inorganic halide perovskites are low-cost solution-processable solar cell materials with photovoltaic properties that rival those of crystalline silicon.
