Abstract :
RF performance flexible thin-film transistors toward green portable devices were realized. The cellulose nanofibrillated fiber (CNF) substrate combined with Si nanomembranes (Si NMs) printing technique enables to fabricate flexible, high-speed and bio-degradable devices. Flexible Si NM thin-film transistors (TFTs) built on the CNF substrate show mobility of 336 cm/v·s and fT and fmax of 2.4 GHz and 5.1 GHz, respectively. This demonstration paves the path to entire green portable devices so as to generate less waste and save more valuable resources.
