Emergent quasiparticles in Euclidean tilings

F. Crasto de Lima and A. Fazzio A material’s geometric structure is a fundamental part of its properties. The honeycomb geometry of graphene is responsible for its Dirac cone, while kagome and Lieb lattices host flat bands and pseudospin-1 Dirac dispersion. These features seem to be particular to a few 2D systems rather than a…

Pair Distribution Function Obtained from Electron Diffraction: An Advanced Real-Space Structural Characterization Tool

João Batista Souza Junior, Gabriel Ravanhani Schleder, Jefferson Bettini, Içamira Costa Nogueira, Adalberto Fazzio, Edson Roberto Leite Summary Atomic-scale structure determination is crucial to the understanding of nanomaterial properties and development of new technologies. Although pair distribution function (PDF) analysis by neutrons and X-ray scattering profile has been used to study materials, electron diffraction can…

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…
