Here, I will discuss modelling ripple curvature inversion dynamic of freestanding graphene using Langevin’s equation and fluctuation - induced current from freestanding graphene. I model one ripple as a Brownian particle in a double well potential with a minimum energy which corresponds to a ripple with concave and convex curvature. The particle is in contact with a thermal bath which is represented by an external white noise source. Interactions with the other ripples which occurs on longer time scales and keep the ripple out of equilibrium are mimicked by an Ornstein-Uhlenbeck colored noise.
