Combinatorial synthesis and characterization of thin film Al1-xRExN (RE = Pr3+, Tb3+) heterostructural alloys
Binod Paudel, John S. Mangum, Christopher L. Rom +8
The potential impact of cation-substituted AlN-based materials, such as Al1-xScxN, Al1-xGaxN, and Al1-xBxN, with exceptional electronic, electromechanical, and dielectric propertie…
Low Leakage Ferroelectric Heteroepitaxial AlScN Films on GaN
Keisuke Yazawa, Charles Evans, Elizabeth Dickey +3
Wurtzite (Al,Sc)N ferroelectrics are attractive for microelectronics applications due to their chemical and epitaxial structural compatibility with wurtzite semiconductors such as…
Defects and Oxygen Impurities in Ferroelectric Wurtzite AlScN Alloys
Naseem Ud Din, Cheng-Wei Lee, Geoff L. Brennecka +1
III-nitrides and related alloys are widely used for optoelectronics and as acoustic resonators. Ferroelectric wurtzite nitrides are of particular interest because of their potentia…
Anomalously Abrupt Switching of Ferroelectric Wurtzites
Keisuke Yazawa, John Hayden, Jon-Paul Maria +4
Ferroelectric polarization switching is one common example of a process that occurs via nucleation and growth, and understanding switching kinetics is crucial for applications such…
