XHEMTs on Ultrawide Bandgap Single-Crystal AlN Substrates
Eungkyun Kim, Yu-Hsin Chen, Naomi Pieczulewski +4
AlN has the largest bandgap in the wurtzite III-nitride semiconductor family, making it an ideal barrier for a thin GaN channel to achieve strong carrier confinement in field-effec…

Shubnikov-de Haas oscillations in coherently strained AlN/GaN/AlN quantum wells on bulk AlN substrates
Yu-Hsin Chen, Jimy Encomendero, Huili Grace Xing +1
We report the observation of Shubnikov-de Haas (SdH) oscillations in coherently strained, low-dislocation AlN/GaN/AlN quantum wells (QWs), including both undoped and -doped str…
