Abstract:
The temperature dependence of the time of hydrogen desorption from single-side hydrogenated graphene is calculated using molecular dynamics simulation. The activation energy ($E_a = (0.75 \pm 0.1)$ eV) and the frequency factor ($A = (2.5\pm 1)\times 10^{15} s^{-1}$) of the desorption are found. This quasi-two-dimensional carbon-hydrogen system is shown to have a relatively low thermal stability, which makes it difficult to use it in practice.
