Current-induced forces in graphene-based nanoelectromechanical systems

Transport currents have distinct effects on the vibrational dynamics of nanoelectromechanical systems. Recently, we have developed a comprehensive scattering-matrix approach to treat out-of-equilibrium current-induced forces [c.f. Phys. Rev. Lett. 107, 036804 (2011)]. We apply our method to the vibrational dynamics of a suspended graphene membrane, paying special attention to the different coupling mechanisms between Dirac fermions and flexural modes in graphene.
