CENIMAT | i3N and CEMOP/UNINOVA researcher Diana Gaspar won the best poster award at the 7th Dresden Nanoanalysis Symposium for her work entitled "Logic Operations with Oxide Field Effect Transistors on Cellulose Substrates”. The awarded work demonstrates that a unique set of characteristics can be combined in planar dual-gate oxide–based field effect transistors with a back floating electrode using cellulose simultaneously as substrate and dielectric. The specific architecture of these transistors allows for all relevant logic operations with just one device, demonstrating the simplification of the production of low power sustainable electronic systems on cellulose based substrates. The Symposium  organized by the Dresden Fraunhofer Cluster Nanoanalysis (DFCNA) was held at Fraunhofer IKTS Dresden (Germany), on August 30, 2019. This year, the symposium stood under the particular motto: "Nano-scale characterization for cutting-edge materials research and sustainable materials development.
