      abstract = {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, magnetostrictive, or in more general  multiferroic materials.
