Ultra-high photocurrent response in a chromia oxide thin film under visible light illumination

Ultra‐Efficient Photocatalytic Properties in Porous Tungsten Oxide/Graphene Film under Visible Light Irradiation

Recently, a growing amount of effort has been devoted to solving the widespread problem of pollution. Photocatalysts have attracted increasing attention for their widespread environmental applications. Here, a classic and simple electrospun technique is used to directly fabricate a porous a tungsten oxide nanoframework with graphene film as a photocatalyst for degradation of pollutants. The as-...

Electrical instability of amorphous indium-gallium-zinc oxide thin film transistors under monochromatic light illumination

Graphene: Ultra‐Efficient Photocatalytic Properties in Porous Tungsten Oxide/Graphene Film under Visible Light Irradiation (Adv. Sci. 12/2015)

In article 1500116, B. Lu and co-workers successfully demonstrate the production of a high performance, highly porous WO 3 nanoframework with graphene film photocatalyst via an electrospinning method. The plentiful exposed graphene nanosheets can great adsorb RhB molecules via – stacking and reduce the recombination rate of electrons and holes.

Remarkably high mobility ultra-thin-film metal-oxide transistor with strongly overlapped orbitals

High mobility channel thin-film-transistor (TFT) is crucial for both display and future generation integrated circuit. We report a new metal-oxide TFT that has an ultra-thin 4.5 nm SnO2 thickness for both active channel and source-drain regions, very high 147 cm(2)/Vs field-effect mobility, high ION/IOFF of 2.3 × 10(7), small 110 mV/dec sub-threshold slope, and a low VD of 2.5 V for low power o...

A Rapid Response Thin-Film Plasmonic-Thermoelectric Light Detector

Light detection and quantification is fundamental to the functioning of a broad palette of technologies. While expensive avalanche photodiodes and superconducting bolometers are examples of detectors achieving single-photon sensitivity and time resolutions down to the picosecond range, thermoelectric-based photodetectors are much more affordable alternatives that can be used to measure substant...
