Advanced full-color image sensor technology enables simultaneous energy harvesting and imaging

Jan 25, 2024 (Nanowerk News) Organic-based optoelectronic technology is increasingly recognized as an energy-efficient solution for low-power indoor electronics and wireless IoT sensors. This is largely due to its superior flexibility and light weight compared to conventional silicon-based devices. Notably, organic photovoltaic cells (OPVs) and organic photodetectors (OPDs) are leading...

Machine learning-driven prediction of strain engineering in graphene

Jan 24, 2024 (Nanowerk News) Two-dimensional (2D) materials like graphene can exhibit exotic quantum mechanical behaviors when subjected to intentional structural distortions. By tweaking interatomic spacings through strain or perturbing electron densities with defects, researchers can finely tune electromechanical characteristics and engineer these atomically thin materials for cutting-edge applications from...
