Computational study of the structure of indium alloys at low temperatures using ab initio methods [Presentation]

Creator:: Shin, Hongsik (Jay)
Abstract:: Presentation for the thesis "Computational Study of the Structure of Indium Alloys at Low Temperatures Using ab initio Methods."
Resource Type:: Presentation

Fabrication and optical measurement of flip-chips for noninvasive electrostatic gating of nanomaterials

Creator:: Nichols, Dublin MacCray
Abstract:: Electrostatic gating of nanomaterials allows researchers to control carrier density and shape potential barriers that confine carriers. Lithographic patterning followed by metal deposition is the standard technique to define electrostatic gates; however, the methods of fabricating these devices often involve harsh processing. For example, taking a material to high temperatures...

A Generalized Scheme for Creating Regge Calculus Models of General Relativity

Creator:: Hanson, Ben R.
Abstract:: Solutions to Einstein's equations are usually found by considering ideal, simplified models. However, if the real world always matched ideal physics models, then farmers would milk black and white spheres. To combat this, Regge calculus was developed as a numerical approximation scheme for general relativity. In Regge calculus curved manifolds...

Development of a Brownian Motion Experiment for an Undergraduate Laboratory Course

Creator:: Wennstrom, Elena
Abstract:: A new class at Oregon State, PH 317: Experimental Physics, is designed to simulate a traditional laboratory research experience for undergraduate students. Several weeks of the class is devoted to Brownian motion experiments. Although this is a common topic for undergraduate lab classes, the experiment still needed some basic exploration...

Detecting Nanohertz Gravitational Waves by Searching for and Timing Millisecond Pulsars

Creator:: Nye, Brandon J.
Abstract:: Detecting gravitational waves is a topic at the forefront of physics. The first gravitational wave was detected by LIGO in 2015. This wave had a frequency in the 10s of Hz. This project is focused on detecting gravitational waves on the nanohertz spectrum using a pulsar timing array. This array...

Effect of Solar System Models on Pulsar Timing Experiments

Creator:: Nicolaysen, Cooper
Abstract:: Gravitational wave (GW) astronomy is a key ingredient in confirming Einstein’s theory of General Relativity and showing how the universe sends ripples through spacetime, distorting distances between two points. The confirmation of high-frequency GWs observed by The Laser Interferometer Gravitational-Wave Observatory (LIGO) in 2015 was a breakthrough in our understanding...

Investigating Grain Boundaries in BaCuS1-xSexF Using Impedance Spectroscopy

Creator:: Horgan, Briony
Abstract:: Impedance spectroscopy is a method of modeling materials with equivalent circuits to determine electrical properties, such as the resistivity and the dielectric constant. We explore impedance spectroscopy, both theoretically and experimentally through applying the method to samples of BaCuS1-xSexF. Grain boundary effects were dominant in the results, and although they...

Application of Coupled Oscillator Model to Terahertz and Optical Control of Plasmon Induced Opacity in Coupled Metamaterials

Creator:: Sprague, Milo X.
Abstract:: Terahertz (THz) frequencies of the electromagnetic spectrum have been underutilized when compared to neighboring microwave and infrared frequencies, largely due to the difficulties controlling and detecting these fields. In a step toward gaining control over THz frequencies, my advisor Dr. Yun-Shik Lee’s group experimentally demonstrated optical-pulse THz-control over a plasmonic...
Resource Type:: Undergraduate Thesis

Photodimerization of Organic Semiconductors in the Strong Coupling Regime

Creator:: Puro, Richard
Abstract:: Organic semiconducting materials have emerged in the last few decades as viable alternatives to inorganics in broad applications from field effect transistors to LEDs to solar cells. Organics provide many benefits over inorganics such as flexibility, sustainability, and reduced cost. However, these materials are more susceptible to degradation in the...

Simulating the Dynein Motor Protein: A Monte Carlo Approach to Achieve Coordinated Stepping

Creator:: Kiatvongcharoen, Jin
Abstract:: The motor protein dynein is responsible for cellular processes such as axonal transport and cell division by delivering vital information along the microtubule track. A failed delivery can cause severe damage to the cell’s functionality and lead to neurological diseases. Despite dynein’s rich history in cellular research, the mechanism of...
