Fall 2011
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...

This thesis explores the dynamics and sensing performance of silicon quantum dot (SiQD) ensembles coupled to the whispering gallery modes (WGMs) of spherical and cylindrical microcavities. The first project investigated the possibility of observing Purcell effects in an ensemble of QDs coupled to...

Spring 2015
This thesis focuses on the photoluminescence (PL) of free-standing silicon quan- tum dots (QDs). Large changes in the emission spectrum were found to occur when the QDs were exposed to different environments while undergoing short-wavelength laser irradiation, a phenomenon that was the main focus...

High Surface Area Nanoelectromechanical Systems via the Integration of Glancing Angle Deposition Thin Films
DownloadFall 2013
High surface area nanoelectromechanical systems (NEMS) are fabricated using glancing angle deposition (GLAD) thin films as the high surface area layer. The GLAD films are deposited on already-released NEMS cantilevers and doubly clamped beams (DCBs) with good uniformity. The resonance frequencies...
