Fall 2023
Plasmonics deals with the collective excitations of light coupled with free electrons in matter. It has widespread use in the fields of biosensing and nanoscale waveguiding due to the enhancement of the electric fields. My thesis deals with an important frontier in the field of plasmonics by...

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...

Molecular self-assembly is the basis of structure in Nature. While of far less complexity than a natural system, the same physical rules apply to simple synthetic designed systems that spontaneously form self-assembled structures and patterns. The self-assembly of block copolymers (BCPs) is an...

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...

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...

Spring 2020
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...

Silicon Nanoparticles from the Inside Out: Exploring the Internal Structure of Silicon Nanoparticles and Its Impact on Their Photoluminescence
DownloadFall 2020
Silicon nanoparticles (SiNPs) have garnered significant attention as a biologically compatible alternative to traditional quantum dots. SiNPs are well suited for a wide range of applications due to their photoluminescence (PL) and chemical properties. These advantageous properties can be...

DNA-assisted Heterogeneous Integration of Micro- and Nanoelectronic Devices: Modeling, Control, and Rational Design of Selective Attachment
DownloadSpring 2018
Heterogeneous integration is an electronic packaging approach that enables the fabrication and assembly of complete electronic subsystems from components fabricated with different substrates and processes. Current commercial techniques like robotic pick-and-place, fluidic self-assembly, and...

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...

Fall 2017
The elements of Group 14 show an extensive range of chemical behaviors. Lying at the boundary between metals and non-metals, some members of Group 14, namely silicon and germanium, are intermediate in their properties. These semiconductors are extremely important in science and technology. Si,...
