Andrew Armstrong

This researcher works on wide-bandgap semiconductor materials and devices, particularly transistors and detectors made from aluminum gallium nitride (AlGaN) and related compounds. Much of the recent work focuses on high electron mobility transistors (HEMTs) that can operate reliably at extreme temperatures, as well as characterizing defects in these materials for applications like radiation-tolerant electronics and light detectors. This research area is largely unrelated to a couple of unrelated titles in the list (e.g., on heatwave coping or geriatric care), which appear to be from a different individual sharing the same name.

Publication output has fluctuated over the past decade, peaking around 2019-2021, dipping in 2022, and partially recovering to a steady rate of roughly 12-20 papers per year in 2023-2025.
