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…
Significant Phonon Drag Enables High Power Factor in the AlGaN/GaN Two-Dimensional Electron Gas
Ananth Saran Yalamarthy, Miguel Muñoz Rojo, Alexandra Bruefach +6
In typical thermoelectric energy harvesters and sensors, the Seebeck effect is caused by diffusion of electrons or holes in a temperature gradient. However, the Seebeck effect can…
High responsivity, low dark current ultraviolet photodetector based on AlGaN/GaN interdigitated transducer
Peter F. Satterthwaite, Ananth Saran Yalamarthy, Noah A. Scandrette +2
An ultraviolet (UV) photodetector employing the two-dimensional electron gas (2DEG) formed at the AlGaN/GaN interface as an interdigitated transducer (IDT) is characterized under o…
