Measuring Brownian motion of MFM-tips & Characterizing mechanical properties of mono-crystalline diamond resonators

In this project two main goals have been pursued: (1) measure the Brownian motion of a magnetic force microscopy-tip (MFM-tip) using either standard optical interferometry or through transmission modulation of a tapered fiber, and (2) measure the mechanical properties (quality factor and resonant frequency) of mono-crystalline diamond resonators...
