Comment on "Sticking of Hydrogen on Supported and Suspended Graphene at Low Temperature"
arXiv:1207.4019 · doi:10.1103/PhysRevLett.113.069601
Abstract
The sticking probability of cold atomic hydrogen on suspended graphene calculated by Lepetit and Jackson [Phys. Rev. Lett. {\bf 107}, 236102 (2011)] does not include the effect of fluctuations from low-frequency vibrations of graphene. These fluctuations suppress the sticking probability for low incident energies ( meV).
