Barrierless procedure for substitutionally doping graphene sheets with boron atoms: ab initio calculations
Renato B. Pontes, A. Fazzio, Gustavo M. Dalpian
Using ab initio methods, we propose a simple and effective way to substitutionally dope graphene sheets with Boron. The method consists of selectively exposing each side of the gra…
Edge effects in Bilayer Graphene Nanoribbons
Matheus P. Lima, A. Fazzio, Antônio J. R. da Silva
We show that the ground state of zigzag bilayer graphene nanoribbons is non-magnetic. It also possesses a finite gap, which has a non-monotonic dependence with the width as a conse…
Hf defects in HfO2/Si
W. L. Scopel, Antonio J. R. da Silva, A. Fazzio
We investigate the possibility that Hf defects exist in the Si channel of HfO2 Si-based metal-oxide-semiconductor devices. We have studied, using ab initio Density Functional Theor…
