In quest of improved nanomechanical sensitivity at larger damping and applications in ambient conditions
DownloadFall 2019
In the current state-of-the-art, a wide variety of devices, from computer clocks to smartphone accelerometers and from pressure gauges to atomic force microscope sensors, rely on mechanical resonators, either in microscale or nanoscale. Nanoscale mechanical resonators have even more potential...

Nanofabrication Methods Towards a Photonically-Based Torque Magnetometer for Measurement of Individual Single-Crystalline Yttrium-Iron-Garnet Microstructures
DownloadSpring 2012
This thesis describes preparation and nanofabrication of single crystalline yttrium-iron-garnet (YIG) for the purposes of ultra-clean torque magnetometry, as well as the design, fabrication, and testing of photonic crystal-based nanoelectromechanical systems for sensing applications. A focused...
