Query: Determination of effective mechanical properties of a double-layer beam
  by means of a nano-electromechanical transducer   We investigate the mechanical properties of a doubly-clamped, double-layer
nanobeam embedded into an electromechanical system. The nanobeam consists of a
highly pre-stressed silicon nitride and a superconducting niobium layer. By
measuring the mechanical displacement spectral density both in the linear and
the nonlinear Duffing regime, we determine the pre-stress and the effective
Young's modulus of the nanobeam. An analytical double-layer model
quantitatively corroborates the measured values. This suggests that this model
can be used to design mechanical multilayer systems for electro- and
optomechanical devices, including materials controllable by external parameters
such as piezoelectric, magnetrostrictive, or in more general multiferroic
materials.
