Spring 2021
Hand injuries, due to impact, are common workplace injuries. Many work gloves afford impact protection through design of add-on components known as bumpers. Glove design criteria are complex (e.g., limitations from human factors, dexterity, use case, hand size variability) and commercial bumpers...

Exploration of Microscopic Structure and Dynamics in Halide Perovskite and Perovskite−Inspired Materials with Solid-State NMR Spectroscopy
DownloadSpring 2022
The work presented in this thesis describes the synthesis, structure, and optical properties of three different classes of halide-based perovskite materials, namely, metal halide perovskites of ABX3 type, halide double perovskites of A2B'B"X6 type, and “vacancy-ordered perovskites” of A2BX6 type...

On a perfect hydrogen-terminated Si(100)-2x1 surface, each surface silicon atom is capped with exactly one atom of hydrogen. When one of the capping hydrogen atoms is removed, the now unsatisfied orbital of the underlying silicon atom is exposed at that site. This site is better known as a...

Spring 2016
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...

Interfacing Silicon-Based Quantum Dots with Proteins for Biological and Sensing Applications
DownloadFall 2020
This dissertation presents the preparation of functional bioinorganic hybrids from silicon-based quantum dots (SiQDs) and enzymes and the use of SiQDs and green fluorescent protein as ratiometric photoluminescent sensors for nerve agents. Chapter 2 discusses the preparation of water-soluble...

Observing and Manipulating Single Electrons Confined to Silicon Dangling Bond Ensembles with Non-Contact Atomic Force Microscopy
DownloadFall 2018
Non-contact atomic force microscopy (nc-AFM) is capable of inducing and resolving single-electron charge transitions of surface adsorbates. Here, these techniques are extended by studying the charge configurations of dangling bond (DB) ensembles on the hydrogen-terminated silicon surface. nc-AFM...

SEM Images of Block Copolymer Templated Patterns from PS-b-P2VP on Silicon with Platinum for Testing with ADAblock
Download2014-07-05
Scanning electron microscope (SEM) images of patterns derived from polystyrene-block-poly(2-vinylpyridine), where the poly(2-vinylpyridine) domains replaced with platinum metal. All samples were annealed for 20 minutes at 200 degrees celsius. Polymers used include PS(23.6k)-b-P2VP(10.4k),...

Spring 2014
The impressive developments in the semiconductor industry over the past five decades have largely been dependent on the ability to continually reduce the dimensions of devices on a chip. However, as critical dimension requirements for these devices approach the limits of photolithography, new...
