Characterizing Optical Signatures of TiO₂ Amorphous Precursors

Creator:: Berry, Patrick
Abstract:: TiO₂ typically crystallizes into three polymorphs: brookite, rutile, and anatase. The phase selection problem in TiO₂ is the lack of understanding what conditions cause amorphous TiO₂ to crystallize into one of its three polymorphs during an annealing process. It has been recently shown that phase selection in TiO₂ is highly...

Molecular Dynamics on REX-GECO1 Reveal Structural Features Governing Fluorescence

Creator:: Rozanov, Nikita
Abstract:: Fluorescent proteins have emerged as an essential toolset for bioimaging, creating a demand for engineering proteins with new and improved fluorescent properties. In this thesis, I explore the atomistic structure of REX-GECO1, a newly engineered protein biosensor that has unique optical properties. Since this protein has no available crystal structure,...

Riesz Transforms on a Sphere

Creator:: Tyma, Troy
Abstract:: Motivated by the Navier-Stokes equations, which are a set of unsolved equations related to fluid motion in R^3, we explored the incompressibility condition and the Neumann boundary problem. After exploring, we noticed that using iterated Riesz transforms of the boundary data could be used to get information about the velocity...

Travelling Wave Analysis of Nonlinear Maxwell Models with Applications to Nonlinear Optics

Creator:: Langlie, Noah
Abstract:: In 1877 John Kerr described an experiment that demonstrated a quadratic change in refractive index in a plate glass placed in a strong external electric field. This results in a nonlinear relationship between the average electric polarization within the materials and the intensity of the applied electric field. This opened...

Fabrication and low-temperature measurement of quantum devices

Creator:: Nichols, Dublin M.
Abstract:: Since the advent of graphene, research on 2D materials has exploded. Countless experiments have uncovered novel properties that emerge when different layered crystals are cleaved down to only a few atomic layers in thickness. The most popular of these non-graphene 2D materials is MoS2, a semiconductor which has been of...

Detection of exciton polaritons in organic thin film TES-ADT

Creator:: Haas, David P.
Abstract:: Exciton polaritons are quasiparticles composed of a quantum superposition of matter and light states that arises from the coupling of a standing wave photon and an exciton. This research has two primary objectives: to design and fabricate a Fabry-Perot microcavity system in which to produce exciton polaritons; and to show...

Terahertz field enhancement in nanoantennas on gallium arsenide

Creator:: Brequigny, Victor
Abstract:: Terahertz (THz) spectroscopy is a great tool not only to study fundamental physical processes such as many-body Coulomb interaction but also to develop ultrafast electronic devices. More specifically, intense THz fields interacting with semiconductors have exhibited strong nonlinear effect involving extreme carrier dynamics. In this experiment, intense THz radiation was...

Deriving relationships between number of observed short gamma ray bursts and viewing angle

Creator:: Micallef, John T.
Abstract:: Gamma ray bursts are some of the brightest events in the entire observable universe. Since the late 1960’s, thousands of gamma ray bursts have been observed and they have been researched extensively. However, there are still many mysteries which remain unsolved. One such mystery is whether or not the viewing...

Multi-Grand, Multi-Canonical, Flat Histogram, Monte Carlo Simulations for the Square Well Fluid

Creator:: Trotter, Cade W.
Abstract:: Currently multi-canonical, and grand canonical Monte Carlo simulations exist, but do not always give all of the necessary information of the system. When using a 1-D (only changing in one variable) broad histogram Monte Carlo method a user would need to run a range of simulations in order to get...
Resource Type:: Undergraduate Thesis

Anti-Reflective Films: Spectroscopy and Ellipsometry of Porous Films

Creator:: Ramm, Joshua J.
Abstract:: The relationship between the index of refraction and the porosity of a material is that the index decreases with respect to the porosity. This property can be used to change the index of refraction of films which allows control of the reflection of the material. This is important because being...
