Second-Order Optical Nonlinearity of AlScN Films Grown By Molecular Beam Epitaxy
Joongwon Lee, Thai-Son Nguyen, Len van Deurzen +8
Alloys of AlN have rapidly emerged as a material platform for nonlinear optics. In this paper, we measure the second-order optical nonlinearity of AlScN films grown directly on nit…
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…
High Mobility Multiple-Channel AlScN/GaN Heterostructures
Aias Asteris, Thai-Son Nguyen, Chuan F. C. Chang +4
Aluminum scandium nitride (AlScN) is a promising barrier material for gallium nitride (GaN)-based transistors for the next generation of radio-frequency electronic devices. In this…
A Compact Model for Polar Multiple-Channel Field Effect Transistors: A Case Study in III-V Nitride Semiconductors
Aias Asteris, Thai-Son Nguyen, Huili Grace Xing +1
A compact analytical model is developed for the mobile charge density of polar multiple channel field effect transistors. Two dimensional electron and hole gases can be potentially…
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…
Lattice-Matched Multiple Channel AlScN/GaN Heterostructures
Thai-Son Nguyen, Naomi Pieczulewsi, Chandrashekhar Savant +6
AlScN is a new wide bandgap, high-k, ferroelectric material for RF, memory, and power applications. Successful integration of high quality AlScN with GaN in epitaxial layer stacks…
Ferroelectric AlBN Films by Molecular Beam Epitaxy
Chandrashekhar Savant, Ved Gund, Kazuki Nomoto +13
We report the properties of molecular beam epitaxy deposited AlBN thin films on a recently developed epitaxial nitride metal electrode Nb2N. While a control AlN thin film exhibits…
Epitaxial lattice-matched AlScN/GaN distributed Bragg reflectors
Len van Deurzen, Thai-Son Nguyen, Joseph Casamento +2
We demonstrate epitaxial lattice-matched AlScN/GaN ten and twenty period distributed Bragg reflectors (DBRs) grown on c-plane bulk n-type GaN substrates by plasma…
