Influence of Graphene Curvature on Hydrogen Adsorption: Toward Hydrogen Storage Devices
The ability of atomic hydrogen to chemisorb on graphene makes the latter a promising material for hydrogen storage. On the basis of scanning tunneling microscopy techniques, we report on site-selective adsorption of atomic hydrogen on convexly curved regions of monolayer graphene grown on SiC(0001). This system exhibits an intrinsic curvature …
