Strain-inducing photochemical chlorination of graphene nanoribbons on SiC (0001)
Copetti, Gabriela; Nunes, Eduardo Horbach; Feijó, Tais Orestes; Galves, Lauren Aranha; Heilmann, Martin; Soares, Gabriel Vieira; Lopes, J. M. J.; Radtke, Claudio (2021) [Journal article]As different low-dimensional materials are sought to be incorporated into microelectronic devices, graphene integration is dependent on the development of band gap opening strategies. Amidst the different methods currently ... -
Thermally-driven H interaction with HfO2 films deposited on Ge(100) and Si(100)
Soares, Gabriel Vieira; Feijó, Tais Orestes; Baumvol, Israel Jacob Rabin; Aguzzoli, Cesar; Krug, Cristiano; Radtke, Claudio (2014) [Journal article]In the present work, we investigated the thermally-driven H incorporation in HfO2 films deposited on Si and Ge substrates. Two regimes for deuterium (D) uptake were identified, attributed to D bonded near the HfO2/substrate ... -
Thermally driven hydrogen interaction with single-layer graphene on SiO2/Si substrates quantified by isotopic labeling
Feijó, Tais Orestes; Rolim, Guilherme Koszeniewski; Corrêa, Silma Alberton; Radtke, Claudio; Soares, Gabriel Vieira (2020) [Journal article]In the present work, we investigated the interaction of hydrogen with single-layer graphene. Fully hydrogenated monolayer graphene was predicted to be a semiconductor with a bandgap of 3.5 eV in contrast to the metallic ...
