Fall 2015
2015 marks the 50th anniversary of Moore's law, which has described the exponential progress in semiconductor patterning technologies, enabling creation of smaller circuitry features at greater densities. These continued hardware developments, economically mass manufactured, have made possible...

Rosette Nanotubes (RNTs) are a class of self-assembled organic nanomaterials generated through the spontaneous hierarchical organization of guanine-cytosine (G˄C) bases with a built-in self-assembling ability. Driven by non-covalent intermolecular forces in solution, G˄C bases self-assemble into...

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...

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...

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...

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...

Germanium nanomaterials have many potential applications based on their size-tunable optical and electronic properties, for example in photodetectors, photovoltaics and non-volatile memory. In this work, the synthesis of Ge nanoparticles by two different methods based on tailorability through the...

Silicon nanocrystals (SiNCs) have been suggested as promising candidates for bioimaging because of their abundance, biocompatibility, and stable photoluminescent properties. However, “naked” SiNCs are insoluble in water and very reactive. As a result, NC surface functionalization is necessary to...
