Direct writing of individual quantum dots
Weikun Zhu, Natalie Ngoh, Shelly Ben-David +9
Quantum light sources capable of generating single photons are fundamental building blocks for photonic quantum technologies. In the ongoing search for an ideal quantum emitter, in…
Van der Waals device integration beyond the limits of van der Waals forces via adhesive matrix transfer
Peter F. Satterthwaite, Weikun Zhu, Patricia Jastrzebska-Perfect +12
Pristine van der Waals (vdW) interfaces between two-dimensional (2D) and other materials are core to emerging optical and electronic devices. Their direct fabrication is, however,…
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…
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…
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…
