Dissipation and nonlinear effects in nanomechanical resonators at low temperatures
Lulla, Kunal (2011) Dissipation and nonlinear effects in nanomechanical resonators at low temperatures. PhD thesis, University of Nottingham.
Nanomechanical resonators have extremely low masses (~ 10−15 kg) and frequencies from a few megahertz all the way up to the gigahertz range. These properties along with a small damping rate make them very useful or ultrasensitive detection applications, now pushing into the realm of zeptonewtons (10−21 N) and zeptograms (10−21 g). On a more fundamental level, nanomechanical resonators are expected to display quantum mechanical effects when cooled down to millikelvin temperatures.
