Mechanically-tunable bandgap closing in 2D graphene phononic crystals
Abstract We present a tunable phononic crystal which can be switched from a mechanically insulating to a mechanically conductive (transmissive) state. Specifically, in our simulations for a phononic lattice under biaxial tension (σ xx = σ yy = 0.01 N m−1), we find a bandgap for out-of-plane phonons...
