Systematic comparison of approximations and functionals in first-principle calculations of aluminum-based III-V ferroelectric nitrides
Alejandro Mercado Tejerina, Peng Chen, Keisuke Yazawa +3
We revisit first-principles predictions of structural, ferroelectric, and electronic properties in aluminum-based III-V nitride alloys, focusing on Al1-xScxN and Al1-xBxN. Using de…
Towards a deeper fundamental understanding of (Al,Sc)N ferroelectric nitrides
Peng Chen, Dawei Wang, Alejandro Mercado Tejerina +4
Density Functional Theory (DFT) calculations, within the virtual crystal alloy approximation, are performed, along with the development of a Landau-type model employing a symmetry-…
Ferroelectricity of Wurtzite AlHfN Heterovalent Alloys
Nate S. P. Bernstein, Daniel Drury, Cheng-Wei Lee +11
Thin films of aluminum hafnium nitride (AlHfN) were synthesized via reactive magnetron sputtering for Hf contents up to = 0.13. X-ray diffraction showed a single…
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…
From Prediction to Experimental Realization of Ferroelectric Wurtzite AlGdN Alloys
Cheng-Wei Lee, Rebecca W. Smaha, Geoff L. Brennecka +3
AlN-based alloys find widespread application in high-power microelectronics, optoelectronics, and electromechanics. The realization of ferroelectricity in wurtzite AlN-based hetero…
