Synthesis and Analysis of Heterostructural Semiconductor Alloy Sn1-xCaxCh (Ch=S, Se) and Nitrides Zn1-xWxN and Zn1-x(W1-yMoy)xN

Creator:: Matthews, Bethany E.
Abstract:: This work explores the synthesis and characterization of the metastable alloys Sn1-xCaxCh (Ch= S, Se) and nitride compounds Zn-W-Mo-N, which have recently been predicted by theorists. Single phase thin films of Sn1-xCaxS are prepared by pulsed laser deposition and radio-frequency magnetron sputtering and of Sn1-xCaxSe are prepared by pulsed laser...

Exchange interaction studies in magnetic semiconductors by neutron scattering

Creator:: Wiren, Zachary Quincy
Abstract:: Theories predict that making a dilute magnetic semiconductor strongly p -type would allow it to remain ferromagnetic at room temperature. This is of intrest as a ferromagnetic semiconductor would allow for a great many applications in the field of spintronics. Neutron scattering experiments were undertaken to better understand the antiferromagnetic...

Hydrogen/deuterium exchange mass spectrometry as a technology platform for studying conformational dynamics in large protein complexes

Creator:: Nirudodhi, Sasidhar N.
Abstract:: Proteins are essential to all biological systems. Proteins participate in numerous cellular processes by interacting with other proteins, other metabolites and membranes in a dynamic environment. Studying the structural and conformational properties of proteins in the solution phase is necessary to understand their protein folding and interaction dynamics. This research...

Label free biosensing with carbon nanotube transistors

Creator:: Leyden, Matthew R.
Abstract:: As electronics reach nanometer size scales, new avenues of integrating biology and electronics become available. For example, nanoscale field-effect transistors have been integrated with single neurons to detect neural activity. Researchers have also used nanoscale materials to build electronic ears and noses. Another exciting development is the use of nanoscale...

Expediting the Generation and Analysis of Amorphous Oxide Computational Models: Modeling Complex Systems Swiftly

Creator:: Buchanan, Jacob C.
Abstract:: In this dissertation, the process of computational modeling of amorphous oxide materials is studied. Amorphous oxides have random atomic arrangements with no long-range structural order which makes it difficult to study structure-property relationships. Despite the difficulties, amorphous oxides have great uses as semiconductors and dielectrics in thin-film transistors. The ability...

Multi-scale Investigation of Bidirectional Feedback Mechanism Between Breast Cancer Cells and Extracellular Matrix

Creator:: Kim, Jihan
Abstract:: Cell migration is fundamental for physiological processes such as immune re-sponses, wound healing and development. It is also a critical characteristic of metastatic cancer cells. An extensive amount of studies have focused on 2D sub-strates in order to understand the mechanism of cancer metastasis. However, much less is known about...

Terahertz Induced Non-linear Electron Dynamics in Nanoantenna Coated Semiconductors at the Sub-picosecond Timescale

Creator:: Stickel, Andrew
Abstract:: This dissertation is an exploration of the material response to Terahertz (THz) radiation. Specifically we will explore the ultrafast electron dynamics in the nonperturbative regime in semiconductors that have been patterned with nanoantenna arrays using broadband, high intensity, THz radiation. Three main semiconductor materials will be studied in this work....

Tracking Photoinduced Primary Events with Femtosecond Stimulated Raman Spectroscopy and Calculations

Creator:: Wang, Yanli
Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is a powerful ultrafast technique which can track photoinduced excited state structural events on femtosecond (fs) to picosecond (ps) timescales. In addition to high temporal and spectral resolutions, FSRS provides a broad spectral window from ca. 100—2000 cm-1 for detection, enabling the direct mapping of...

The optical properties of multi-scale plasmonic structures and their applications in optical characterization and imaging

Creator:: Kuhta, Nicholas Anthony
Abstract:: The optical response of metallic structures is dominated by the dynamics of their free electron plasma. Plasmonics, the area of optics specializing in the electromagnetic behavior of heterogeneous structures with metallic inclusions, is undergoing rapid development, fueled in part by recent progress in experimental fabrication techniques and novel theoretical approaches....

Terahertz imaging and spectroscopy of carbon-based and semiconductor nanostructures

Creator:: Tomaino, Joseph L.
Abstract:: This thesis will cover work that I have completed relating to the field of terahertz (THz) science. My work has consisted of generating tunable, narrowband THz pulses in a table-top optical setup and using both narrow- and broadband THz pulses to study various material systems. Broadband THz pulses were used...
