Autor: Giuseppe Valerio Bianco, Alberto Sacchetti, Marco Grande, Antonella D’Orazio, Antonella Milella, Giovanni Bruno
Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-11 (2022)
Abstract Nitrogen substitutional doping in the π-basal plane of graphene has been used to modulate the material properties and in particular the transition from hole to electron conduction, thus enlarging the field of potential applications. Dependi

Extraordinary low sheet resistance of CVD graphene by thionyl chloride chemical doping
Autor: Alberto Sacchetti, Antonella Milella, Giovanni Bruno, Giuseppe Valerio Bianco, Pio Capezzuto, Antonella D'Orazio, Marco Grande
Chemical doping is an effective way to increase the conductivity of graphene. Despite the efforts made by many to achieve p-doping, mainly on CVD graphene, by using a variety of oxidant agents, there is still space to evaluate and optimize methodolog
