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…
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…
Accelerating Electronic Stopping Power Predictions by 10 Million Times with a Combination of Time-Dependent Density Functional Theory and Machine Learning
Logan Ward, Ben Blaiszik, Cheng-Wei Lee +3
Knowing the rate at which particle radiation releases energy in a material, the stopping power, is key to designing nuclear reactors, medical treatments, semiconductor and quantum…
