(2020): Investigation of the Interaction, Nonlinear and Dissipation Effects in Nano-Membrane Resonators by Optical Interferometry |
Nanomechanical membrane resonators are extensively used in a variety of applications due to their high quality factor and sensitive response in the linear working range. The quantitative characterization of mechanical properties of nanomechanical resonators paves the way to understand the vibrational dynamics of nanomechanical systems and provides the opportunity to extend the application into nonlinear regime. In the nonlinear regime, the nanomechanical systems present tremendous vibrational and coupling behavior which can provide massive information beyond the linear regime. Thus extending the investigation into nonlinear is significantly important. In this thesis, we present experimental studies of the bending waves of freestanding silicon nitride (SiN) nanomembrane resonators in different dynamic regimes by using optical profilometry, such as Imaging White Light Interferometer (IWLI) and Michelson Interferometer (MI), in varying environments such as pressure and temperature.
