Tunable Nonlinear Landscapes in Graphene Nanoelectromechanical Systems

Abstract Nonlinear nanomechanical resonators give convenient solid-state access to classical analogs of extreme nonlinear optics and to phononic signal processing. Here we report integer harmonic generation, phononic frequency sideband comb, and reverse period-doubling dynamics i...

Electron Beam Radiolysis-Assisted Growth of Rutile TiO2 Thin Films

Abstract A new approach for growing crystalline thin films is developed that takes advantage of electron beam radiolysis as a constructive force to rearrange atoms into a crystalline structure. It is demonstrated that by irradiating the surface of a TiO2 film by an electron beam...
