Edge-driven nanomembrane-based vertical organic transistors showing a multi-sensing capability

Nawaz, A.; Merces, L.; de Andrade, D.M.; Camargo, D.H.S.; Bufon, C.C.B. Abstract This work presents the development of a vertical organic field-effect transistor (VOFET) platform. The devices are processed entirely via microfabrication and photolithography techniques, in the cleanroom facilities of the Brazilian Nanotechnology National Laboratory (LNNano/CNPEM). The first novelty of our VOFET architecture stems from…

Rectification ratio and direction controlled by temperature in copper phthalocyanine ensemble molecular diodes

Carolina Sergi Lopes, Leandro Merces, Rafael Furlan de Oliveira, Davi Henrique Starnini de Camargo, Carlos César Bof Bufon Abstract Organic diodes and molecular rectifiers are fundamental electronic devices that share one common feature: current rectification ability. As both present distinct spatial dimensions and working principles, the rectification of organic diodes is usually achieved by interface…
