Title (EN) MULTI-DOPED GRAPHENE AND METHOD FOR PREPARING THE SAME
(FR) GRAPHÈNE MULTI-DOPÉ ET SON PROCÉDÉ DE PRÉPARATION
Abstract: front page image
(EN)A graphene doped with different dopants and a method for preparing the same are disclosed. A method for preparing a multi-doped graphene includes: mixing a metal-based dopant and at least one organic-based dopant to prepare a doping solution; stacking a graphene layer on a substrate; and doping the graphene layer with the doping solution that includes the metal-based dopant and the at least one organic-based dopant. The method allows maintaining the transparency of the prepared graphene and minimizing the sheet resistance of the graphene while not damaging a substrate on which the graphene is stacked.
(FR)L'invention concerne également un graphène multi-dopé avec différents dopants et son procédé de préparation. Un procédé de préparation d'un graphène multi-dopé comprend : le mélange d'un dopant à base de métal et d'au moins un dopant organique pour préparer une solution de dopage; l'empilage d'une couche de graphène sur un substrat; et le dopage de la couche de graphène avec la solution de dopage qui comprend le dopant à base de métal et le ou les dopants organiques. Le procédé permet de maintenir la transparence du graphène préparé et de réduire au minimum la résistance de la feuille du graphène tout en n'endommageant pas un substrat sur lequel le graphène est empilé.
