Laser-generated CuPdAgPtAu High-Entropy Alloy Nanoparticles -- Thermal Segregation Threshold and Elemental Segregation
Felix Pohl, Robert Stuckert, Florent Calvo +5
High-entropy alloy nanoparticles synthesized via laser ablation in liquid are promising for catalysis due to their ability to form simple solid solutions despite chemical complexit…
Effect of TiPd(Ni) on the Transformation Behavior in Sputtered Ti-rich TiNiPd Shape Memory Alloys
Lars Bumke, Niklas Wolff, Lorenz Kienle +1
TiNiPd based shape memory alloys (SMAs) share similar microstructural features as TiNiCu-based SMAs known for their exceptional resistance to functional fatigue due to their high c…
Interfacial Polarization Switching in Al0.92Sc0.08N/GaN Heterostructures Grown by Sputter Epitaxy
Niklas Wolff, Georg Schönweger, Redwanul Md. Islam +4
The integration of ferroelectric nitride thin films such as Al1-xScxN onto GaN templates could enable enhanced functionality in novel high-power transistors and memory devices. Thi…
Improved Leakage Currents and Polarity Control through Oxygen Incorporation in Ferroelectric Al0.73Sc0.27N Thin Films
Md Redwanul Islam, Niklas Wolff, Georg Schönweger +8
This article examines systematic oxygen (O)-incorporation to reduce total leakage currents in sputtered wurtzite-type ferroelectric Al0.73Sc0.27N thin films, along with its impact…
