NO2 sensing characteristics by α-Fe2O3 nanorod arrays with atomic layer deposited amorphous Al2O3 overlayer

Nano Express
We have grown α -Fe _2 O _3 nanorods by solution processing followed by the deposition of Al _2 O _3 overlayer using atomic layer deposition. Al _2 O _3 layer was deposited for two different thicknesses 4 nm and 8 nm and a post-deposition annealing at ...

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.
