Shubnikov-de Haas oscillations of two-dimensional electron gases in AlYN/GaN and AlScN/GaN heterostructures
Yu-Hsin Chen, Thai-Son Nguyen, Isabel Streicher +4
AlYN and AlScN have recently emerged as promising nitride materials that can be integrated with GaN to form two-dimensional electron gases (2DEGs) at heterojunctions. Electron tran…
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…
Epitaxial high-K AlBN barrier GaN HEMTs
Chandrashekhar Savant, Thai-Son Nguyen, Kazuki Nomoto +8
We report a polarization-induced 2D electron gas (2DEG) at an epitaxial AlBN/GaN heterojunction grown on a SiC substrate. Using this 2DEG in a long conducting channel, we realize u…
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…
