Ripples are intrinsic disorder of graphene sheets.

Ripples are intrinsic disorder of graphene sheets. Correct Answer True

The localized π-electrons lead to asymmetric distribution of carbon-carbon bond lengths. This forces the graphene lattice to become non-planar in order to minimize free energy. Eventually, ripples are formed with heights upto 1nm. So, thermal fluctuations induced ripples are intrinsic features on graphene sheets.
