Temperature Dependence of Sensitivity of 2DEG-Based Hall-Effect Sensors
Hannah S. Alpert, Caitlin A. Chapin, Karen M. Dowling +4
The magnetic sensitivity of Hall-effect sensors made of InAlN/GaN and AlGaN/GaN heterostructures was measured between room temperature and 576°C. Both devices showed decreasing vol…
Clocking the formation of today's largest galaxies: Wide field integral spectroscopy of Brightest Cluster Galaxies and their surroundings
Louise O. V. Edwards, Matthew Salinas, Steffanie Stanley +8
The formation and evolution of local brightest cluster galaxies (BCGs) is investigated by determining the stellar populations and dynamics from the galaxy core, though the outskirt…
Gallium Nitride Photodetector Measurements of UV Emission from a Gaseous CH4/O2 Hybrid Rocket Igniter Plume
Hannah S. Alpert, Ananth Saran Yalamarthy, Peter F. Satterthwaite +6
Owing to its wide (3.4 eV) and direct-tunable band gap, gallium nitride (GaN) is an excellent material platform for UV photodetectors. GaN is also stable in radiation-rich and high…
Micro-Tesla Offset in Thermally Stable AlGaN/GaN 2DEG Hall-effect Plates using Current Spinning
Karen M. Dowling, Hannah S. Alpert, Ananth Saran Yalamarthy +5
This letter describes the characterization of a low-offset Hall-effect plate using the AlGaN/GaN two-dimensional electron gas(2DEG). Four-phase current spinning was used to reduce…
Effect of Geometry on Sensitivity and Offset of AlGaN/GaN and InAlN/GaN Hall-effect Sensors
Hannah S. Alpert, Karen M. Dowling, Caitlin A. Chapin +5
The current- and voltage-scaled sensitivities and signal-to-noise ratios (SNR) (with respect to thermal noise) of various octagonal AlGaN/GaN and InAlN/GaN Hall-effect sensors were…
Stellar Populations of BCGs, Close Companions and Intracluster Light in Abell 85, Abell 2457 and IIZw108
Louise O. V. Edwards, Hannah S. Alpert, Isabella L. Trierweiler +2
We present the first results from an integral field (IFU) spectroscopic survey of a 75kpc region around three Brightest Cluster Galaxies (BCGs), combining over 100 IFU fibres to st…
