Accelerating point defect simulations using data-driven and machine learning approaches
Arun Mannodi-Kanakkithodi, Menglin Huang, Prashun Gorai +1
Point defects in solid-state materials are now routinely simulated using large supercell structures, requiring efficient quantum mechanical solutions. Data-driven and machine learn…
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…
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…
GdWN is a Nitride Perovskite
Rebecca W. Smaha, John S. Mangum, Neha Yadav +8
Nitride perovskites N are an emerging and highly under-explored class of materials that are of interest due to their intriguing calculated ferroelectric, optoelectronic, an…
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…
Structural and Optoelectronic Properties of Thin Film LaWN
Rebecca W. Smaha, John S. Mangum, Ian A. Leahy +9
Nitride perovskites are an emerging class of materials that have been predicted to display a range of interesting physics and functional properties, but they are under-explored due…
