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...

High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

Metallic thin films for NEMS/MEMS: from fundamental behaviour to microstructural design and fabrication
DownloadFall 2011
The main focus of this thesis is the study of thin metal films in microelectromechanical/nanoelectromechanical systems (MEMS/NEMS), ranging from application to fundamental behaviour. The use of metallic structural components is desirable since they are electrically conductive, optically reflective...

This work investigates the use of nanoimprint lithography for creating nanoscale resonator devices for applications in mass sensing. A bilayer resist consisting of PMMA 495/LOR 3A allowed the ideal imprint yield for resonators with widths ranging from 300 nm down to 120 nm. Resonators with...
