Atomically-thin Al2O3 dielectric films for metal-insulator-metal tunnel junctions
(University of Kansas, 2017-12-31)Metal-Insulator-Metal tunnel junctions (MIMTJ) are a core building block for a variety of microelectronics including Magnetic Tunnel Junctions (MTJs) for magnetic memory and Josephson Junctions (JJs) for quantum computers. ... -
Measurements on the thermal conductivities of mercury, sodium, and sodium amalgams
(University of Kansas, 1936) -
J/Ψ production in ultra-peripheral proton-lead and lead-lead collisions with CMS
(University of Kansas, 2017-12-31)This thesis reports on photoproduction of exclusive J/ψ mesons in ultra-peripheral PbPb and pPb collisions at √sNN = 2.76 TeV, and 5.02 TeV, respectively, from the CMS experiment at the LHC. For PbPb collisions, there is ... -
Improved Energy Reconstruction with Generalized Particle Decays by Applying Multiple Constraints
(University of Kansas, 2017-12-31)Mass constrained fitting is a technique that improves jet energy resolution. The fit is performed by assigning a well-known mass to a decaying particle and minimizing a χ 2 consisting of the constituent particle’s measured ... -
Multiscale Optoelectronic Properties of Nanostructured Zinc Oxide Ultraviolet Photodetectors
(University of Kansas, 2017-05-31)Zinc oxide nanostructures, such as ZnO nanowires (NWs) and quantum dots (QDs) were fabricated via solution routes and incorporated with graphene to form high-performance ZnO/graphene nanohybrid ultraviolet optoelectronic ... -
Interlayer Charge Transfer in van der Waals Heterostructures Formed by Transition Metal Dichalcogenide Monolayers
(University of Kansas, 2017-05-31)Since the discovery of graphene and its outstanding chemical, optical, and mechanical properties, other layered materials have been fiercely hunted for through physical and chemical means. Thanks to their van der Waals ... -
The effect of temperature on the natural ionization of gases in an iron chamber
(University of Kansas, 1929) -
External Plasma Interactions with Nonmagnetized Objects in the Solar System
(University of Kansas, 2017-05-31)The absence of a protecting magnetic field, such as the dipole magnetic field around Earth, makes the interaction of solar wind with unmagnetized objects particularly interesting. Long-term evolution of the object’s surface ... -
Nonlinear Optical Spectroscopy of Two-Dimensional Materials
(University of Kansas, 2017-05-31)Nonlinear optical properties of two-dimensional (2D) materials, such as transition metal dichalcogenides (TMDs), graphene, black phosphorus, and so on, play a key role of understanding nanoscale light-matter interactions, ... -
"A New and Generic Two-Dimensional Model for Studying Channeling Radiation with Relativistic Electron Beams"
(University of Kansas, 2017-05-31)In 2016, Fermilab Accelerator and Technology Facility (FAST) conducted an experiment to generate a discrete and potentially tunable hard X-ray channeling radiation emissions in the 40-150 KeV energy range using a new 50 ... -
Charting the Unknown: A Hunt in the Dark
(University of Kansas, 2017-08-31)Astrophysical and cosmological observations have pointed strongly to the existence of dark matter in the Universe, yet its nature remains elusive. It may be hidden in a vast unknown parameter space in which exhaustively ... -
Mathematical Methods for studying DNA and Protein Interactions
(University of Kansas, 2017-08-31)Deoxyribnucleic Acid (DNA) damage can lead to health related issues such as developmental disorders, aging, and cancer. It has been estimated that damage rates may be as high as 100,000 per cell per day. Because of the ... -
Plasma Cascade in Kerr Black Hole Magnetospheres
(University of Kansas, 2017-08-31)Electromagnetic, radiative, and plasma processes around black holes in active galaxies determine how relativistic jets are launched and the efficiency at which the black hole energy is extracted via the Blandford-Znajek ... -
Hydrodynamic Flow Fluctuations in √sNN = 5.02 TeV PbPb Collisions
(University of Kansas, 2017-08-31)The collective, anisotropic expansion of the medium created in ultrarelativistic heavy-ion collisions, known as flow, is characterized through a Fourier expansion of the final-state azimuthal particle density. In the Fourier ... -
photPARTY: Python Automated Square-Aperture Photometry
(University of Kansas, 2017-05-31)As CCD’s have drastically increased the amount of information recorded per frame, so too have they increased the time and effort needed to sift through the data. For observations of a single star, information from millions ... -
