Formation and stability of highly conductive semitransparent copper Meso-grids covered with graphene
Álvarez Fraga, Leo ; Bartolomé Vílchez, Javier ; Aguilar Pujol, Montserrat X. ; Ramírez Jiménez, Rafael ; Prieto, Carlos ; Alicia de, Andrés | Elsevier | 2019-11-01We report on the formation of highly stable and robust hybrid semitransparent electrodes based on a percolated mesoscale copper grid covered with graphene. Copper films sputtered on transparent substrates are used to synthesize graphene by CVD a[...]texto impreso
Grain selective Cu oxidation and anomalous shift of graphene 2D Raman peak in the graphene-Cu system
Bartolomé Vílchez, Javier ; Cremades Rodríguez, Ana Isabel ; Álvarez Fraga, Leo ; Aguilar Pujol, Montserrat X. ; Cortijo Campos, Sandra ; Prieto de Castro, Carlos ; Andrés Miguel, Alicia de | IOP Publishing | 2019-01Understanding the interaction between graphene and its supporting substrate is of paramount importance for the development of graphene based applications. In this work the interplay of the technologically relevant graphene-Cu system is investiga[...]texto impreso
Aguilar Pujol, Montserrat X. ; Ramírez Jiménez, Rafael ; Xifre Pérez, Elisabet ; Cortijo Campos, Sandra ; Bartolomé Vílchez, Javier ; Marsal, Lluís F. ; Andrés, Alicia de | MDPI | 2020-05The detection of Raman signals from diluted molecules or biomaterials in complex media is still a challenge. Besides the widely studied Raman enhancement by nanoparticle plasmons, interference mechanisms provide an interesting option. A novel ap[...]
