Photoexfoliation of Graphene from Graphite: An Ab Initio Study Yoshiyuki Miyamoto,
... As our key result, we find that exposing the graphite surface to a laser pulse causes detachment of the topmost layer with a kinetic energy exceeding 1 eV=atom. This energy is orders of magnitude larger than the weak interlayer interaction energy in graphite [15,24]. Consequently, our results should ...
