Study of the vibrational modes in BeSiN2 and BeGeN2
The heterovalent, ternary, II-IV-N2 compounds BeGeN2 and BeSiN2 are related to GaN. Conceptually, one can replace two of the four group-III cations surrounding each nitrogen anion by a group II element, and the other two by a...

Continuous Liquid Interface Production of Gas Electron Multipliers
Gas Electron Multipliers (GEMs) are detector tools used in high-energy particle physics research to detect weak ionizing radiation. GEMs are designed small enough to generate strong electric fields in small areas, allowing them to increase the signal from...
Mechanical Topological Insulators
Jacob Moran with Harsh Mathur
In this project we will study mechanical topological insulators. Yu and Mathur have found that the elastic modes of bilayer graphene are analogous to the electronic states of topological insulators. Using a continuum elasticity model they find that the elastic waves are...

Constraining the Topology of the Universe: A Generalization of Flat Manifold Parameter Spaces
An open question for cosmologists concerns whether the universe is infinite or finite. For a flat cosmology, the topology of the universe can take on any one of 18 manifolds, some of which are...

Black Phosphorus Field Effect Transistors: Device Physics and Performance
We are nearing the end of Moore's law. Silicon based transistors, the amazing technology that led to the huge growth of Silicon Valley, are rapidly approaching a point where they will not be able

Calculation of Magnetic Interactions Between Magnetic Nanoparticles
One problem yet to be completely solved in the world of physics and material science is the ferromagnetic fluid or fluid that has a magnetization outside of external magnetic fields. Fluids that respond to magnetic fields have been studied...

Optimizing the Search for Order Parameters in Quasicrystals
This research seeks to apply existing phase transition theory to quasicrystals in order to develop a better understanding for their underlying physical theory. This will consist of running simulations of hard tetrahedral particles that tend to develop quasicrystalline...

Informing Architectural-Acoustical Design with Musical Details
Music performance spaces are currently subject to vague design guidelines and long calibrations after their completion. However, the field of architectural acoustics is developing many new, more precise means of testing proposed designs; those new processes are best complemented by...

Growth of Indium MonoSelenide for 2D Semiconductor Devices
Two-dimensional (2D) van der Waals (vdW) materials with structures similar to graphene and graphite have emerged as a major research area in materials and condensed matter physics research. While an abundance of recent efforts were spent on transition...

Investigating the Durability and Reliability of PERC Solar Cells with Accelerated Weathering
Abstract - PERC (passivated emitter rear cell) monocrystalline silicon photovoltaic cells have higher efficiency than Al-BSF (aluminum back surface field) silicon photovoltaic cells, but these new PERC cell designs do not have well established...
