Using the classical molecular dynamics simulations, we have investigated the thermally-excited ripples of the multilayer graphenes at different temperatures, and compared them with those of the single- and doublelayer graphene. It is found that: 1) the ripples in multilayer graphene are intrinsic with a characteristic size of about 100 at room tempe- rature, increasing with increase of temperature; at the same time, the ripples height also increases with the temperature; 2) the ripples intralayer height-height correlation functions for the multilayer graphene follow a power-law behavior, Gh(q) q-; the scaling exponent decreases as temperature increases. Moreover, the scaling exponents are different for different types of multilayer graphene even at the same temperature. All these phenomena result from the anharmonic effects which are induced by the temperature and the interlayer interactions.
