Matthew Krupcale with Philip FengNanoscale Membrane Structures for Radiation DetectionRadiation detectors are used in a wide range of environments from medical to nuclear and research facilities. The use of nanoscale membranes for radiation detection has largely been unexplored, despite having interesting optoelectronic properties. This project focuses on conducting a...

Photovoltaic Degradation Analysis and Two Diode Simulated Models
An understanding of the degradation process of photovoltaic modules during real world use is crucial to extending their lifetime and reliability. The degradation that occurs during normal use of a panel can be...

Measuring Scattering, Absorption, and Reflection Properties for Filters in the South Pole Telescope
A current problem with many ground-based telescope experiments, such as the South Pole Telescope, is that the optical loading on the detectors is undesirably high. In the South Pole Telescope, millimeter-wavelength photons from...

Significance of Image Heterogeneity in Multi-Modality Medical Imaging
Heterogeneous features have been observed in clinical PET-CT and PET-MRI imaging of tumors. The significance of this heterogeneity is not well understood but may have prognostic value for clinicians. To advance understanding of this parameter, an investigation of...
Christopher Miller with Philip FengPhysics and Instrumentation of Growing MoS2 CrystalsThis senior project is aimed at developing physical vapor deposition, transfer printing, and other related techniques for making ultra thin semiconducting membrane structures, which have potential to be engineered into transducers and sensors (e.g., gas sensors or single-particle detectors)...

Stochastic Differential Equations Driven by Compound Poisson and Lévy Processes
Stochastic differential equations (SDEs) provide a rigorous setting for investigating the dynamics of systems subject to “noise,” by which we mean source terms whose behavior is not deterministic, but governed by a probability distribution. The...
Andrew O’Desky with John F. R. DuncanDynkin Diagrams and the Groups of Umbral MoonshineElliptic curves are number theoretic objects with many important applications in mathematics, cryptography, string theory and beyond. The supersingular elliptic curves in prime characteristic constitute a special family, and in 1974 Andrew Ogg showed that there...

Persistent Switch Design for MgB2 Superconducting Magnet
High quality MRI imaging requires that the main magnetic field remain temporally stable to within 0.1 ppm per hour, which is achieved by operating the main superconducting magnet in persistent current mode. After a power supply...

A Novel Route to Synthesis of Sn3N4 and ZnSnN2 Thin Films
III-Nitride direct band-gap materials have long been used in opto-electronic applications ranging from consumer high density optical storage devices and LED’s to ultraviolet research lasers.1-2 By replacing the group-III sublattice with an II-IV ordered pair...

The Accelerating Universe and Vacuum Energy
During his senior project, Daniel Pfeffer will investigate the acceleration of the Universe. He will explore whether or not it is possible to screen the effect of a large vacuum energy and give rise the amount of acceleration currently...
