Dec 16, 2023 (Nanowerk Spotlight) Ever since the first observations of light scattering by particles in the 19th century, achieving ideal optical transparency has posed an enduring grand challenge. Natural solid things like rocks or crystals tend to make light zigzag or spread out in different directions. This happens because...
Ultrafast lasers map electrons ‘going ballistic’ in graphene with implications for next-gen electronic devices
Dec 15, 2023 (Nanowerk News) Research appearing in ACS Nano ("Spatiotemporal Observation of Quasi-Ballistic Transport of Electrons in Graphene"), reveals the ballistic movement of electrons in graphene in real time. The observations, made at the University of Kansas’ Ultrafast Laser Lab, could lead to breakthroughs in governing electrons in semiconductors,...
