During the last years optomechanics has developed into a wide playground, allowing the study of quantum mechanics in a literal sense. Here, a light field is coupled to the mechanical motion of a resonator and exploited to cool down the mechanical mode eventually to its quantum mechanical ground state. In our case, the light field is realized in form of microwave photons in a superconducting on-chip cavity and the mechanical oscillator as freely suspended, nanometer-sized beam. This on-chip layout allows implementing experiments at low temperatures in a straightforward way. We present first experimental results on the characterization of nanometer-sized beams and beam-resonator hybrids.
