Local distortions as a source of piezoelectric/stiffness decoupling in B-doped AlScN
Laszlo Wolf, Geoff L. Brennecka, Vladan Stevanović
We present a first-principles analysis of the wurtzite pseudo-ternary (Al,Sc,B)N to elucidate the structural origin of a decoupling between stiffness and piezoelectric res…
First-principles study of the phase competition, mechanical and piezoelectric properties of pseudo-binary (SiC)(AlN) alloy
Laszlo Wolf, Geoff L. Brennecka, Vladan Stevanović
The ongoing search for new piezoelectric materials offering adequate balance between piezoelectric response and other application-relevant properties has lead to the investigation…
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…
