Deposition and characterization of ZnSnSb2 for phase transition studies
ZnSnSb2 (zinc tin antimonide) is predicted to have interesting crystal structures, phase transitions, and thermoelectric properties that have not yet been carefully confirmed by experiment. The objective of this study is to produce, characterize...

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...

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...

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...

Photorefractive properties of liquid crystal-filled bacterial cellulose mats
The photorefractive effect is a phenomenon associated with nonlinear optical materials in which the refractive index of the material varies with the application of light. One demonstration of this effect is dynamic holography. Energy transfer between diffracted beams...

Developing New Techniques for Characterizing Optical Properties of Millimeter Wavelength Detectors
Poster
Characterization of the Cosmic Microwave Background (CMB) is a major focus of modern experimental research in cosmology and astrophysics. CMB photons carry important information that could expand our understanding about the origin and content of...
Rachel Capelouto with Rolfe PetschekOrientation Waves in Colloidal Crystals Crystals are usually thought of as the condensation of density waves. However, in some systems, notably blue phase liquid crystals, and, according to recent results in our group also hard tetrahedra, the formation of a crystal comes from the condensation...
Sean Kinzler with Michael MartensDesign of a Persistent Switch for 0.35T Magnesium DiBoride Superconducting MagnetsRecent progress in magnet design and persistent joints using for the magnesium diboride, MgB2, superconductor has made clear the increasingly important role of the persistent switch in magnet quench protection. The persistent switch is used...
Vipul Malik with Philip FengImproving the I-V characteristics of Molydinium DiSulfide transistors h-Boron NitrideMolybdenum disulfide (MoS2) transistors have attracted considerable attention. Molybdenum disulfide (MoS2) transistors on boron nitride (BN) substrates in particular show interesting I-V characteristics. Unfortunately these transistor devices currently exhibit undesirable I-V characteristics at low temperatures due to...
Christopher Wagner with Xuan GaoInvestigating the growth mechanism of atomically thin transition metal dichalcogenidesMonolayers of transition metal dichalcogenides (TMDCs), such MoS2 and MoSe2 , have been the subject of increased interest due to their promising potential in nanoelectronics, optoelectronics, and other fields. To date, the synthesis of large area...
