Ultrastable Self‐Cross‐linkable Electro‐Optic Materials Based on a Bisanthracene Scaffold

open access: yesAdvanced Electronic Materials, EarlyView.
A novel bisanthracene‐based self‐cross‐linkable electro‐optic chromophore (TD2) is developed. TD2 exhibits a high r33 of 141 pm/V and a cross‐linked Tg up to 195 °C, retaining 99.75% of its initial EO response after 500 h at 85 °C, showing record‐high thermal stability for single‐molecule self‐cross‐linking EO materials.

High‐Performance Solar‐Blind Photodetectors Enabled by Post‐Annealing Optimization of Solution‐Processed Ga2O3 Films

open access: yesAdvanced Electronic Materials, EarlyView.
Post‐annealing atmosphere and temperature are optimized to regulate oxygen‐related defect states in solution‐processed Ga2O3 films. The optimized H2/N2 annealing enables enhanced photoconductive gain while maintaining low dark current, leading to high‐performance solar‐blind photodetectors with a responsivity of 7.5 × 102 A W−1 under 254 nm ...
