Comment on Sticking of Hydrogen on Supported and Suspended Graphene at Low Temperature


Abstract in English

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 ($lesssim 15$ meV).
