Molybdenum Trioxide Gates for Suppression of Leakage Current in InAlN/GaN HEMTs at 300°C
Caitlin A. Chapin, Savannah R. Benbrook, Chloe Leblanc +1
Because high electron mobility transistors (HEMTs) often exhibit significant gate leakage during high-temperature operation, the choice of Schottky metal is critical. Increased gat…
A Laterally Vibrating Lithium Niobate MEMS Resonator Array Operating at 500°C in Air
Savannah R. Benbrook, Caitlin A. Chapin, Ruochen Lu +3
This paper is the first report of the high-temperature characteristics of a laterally vibrating piezoelectric lithium niobate (LiNbO) MEMS resonator array up to 500°C in air.…
Effect of Proton Irradiation Temperature on Zinc Oxide Metal-Semiconductor-Metal Ultraviolet Photodetectors
Thomas Heuser, Caitlin Chapin, Max Holliday +2
The electrical and structural characteristics of 50 nm zinc oxide (ZnO) metal-semiconductor-metal (MSM) ultraviolet (UV) photodetectors subjected to proton irradiation at different…
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…
Stable Operation of AlGaN/GaN HEMTs at 400C in air for 25 hours
Saleh Kargarrazi, Ananth Saran Yalamarthy, Peter F. Satterthwaite +3
In this letter, we report the operation of AlGaN/GaN HEMTs with Pd gates in air over a wide temperature range from 22C to 500C. The variation in the threshold volta…
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…
