Spectroscopy of mechanical dissipation in micro-mechanical membranes [PDF]
, 2011 We measure the frequency dependence of the mechanical quality factor (Q) of SiN membrane oscillators and observe a resonant variation of Q by more than two orders of magnitude. The frequency of the fundamental mechanical mode is tuned reversibly by up to
