Nanomechanical resonators: fundamental questions and current applications

March 7, 2017, 5 p.m.


The field of nanomechanics has been flourishing in the past couple of years. In particular the prospect of creating ultra-sensitive mass and force sensors was a major driving force. Moreover, the possibility to study fundamental aspects of (quantum) mechanical properties at the nanometer scale makes this subject very attractive and interesting. The low mass and small sizes of typical resonator devices allow for very high resonator frequencies and high quality factors. However, it was also found that nonlinear effects - like Duffing nonlinearity and nonlinear damping - play an important role for such systems. In this lecture I will introduce some of the relevant nonlinear properties, their physical origin and consequences. Additionally, recent and prospect developments in the field will be discussed.
