Atomic resolution observations of silver segregation in a [111] tilt grain boundary in copper
Lena Langenohl, Tobias Brink, Gunther Richter +2
Alloying a material and hence segregating solutes to grain boundaries is one way to tailor a material to the demands of its application. Direct observation of solute segregation is…
Terahertz spin-to-charge current conversion in stacks of ferromagnets and the transition-metal dichalcogenide NbSe
Lukáš Nádvorník, Oliver Gueckstock, Lukas Braun +16
Transition-metal dichalcogenides (TMDCs) are an aspiring class of materials with unique electronic and optical properties and potential applications in spin-based electronics. Here…
Highly stable, reactive and ultrapure nanoporous metallic films
Hyunah Kwon, Hannah-Noa Barad, Alex Ricardo Silva Olaya +5
Nanoporous metals possess unique properties attributed to their high surface area and interconnected nanoscale ligaments. They are mostly fabricated by wet synthetic methods involv…
Plastic forming of metals at the nanoscale: interdiffusion-induced bending of bimetallic nanowhiskers
Yuanshen Qi, Gunther Richter, Eylul Suadiye +2
Controlled plastic forming of nanoscale metallic objects by applying mechanical load is a challenge, since defect-free nanocrystals usually yield at near theoretical shear strength…
Rational Strain Engineering in Delafossite Oxides for Highly Efficient Hydrogen Evolution Catalysis in Acidic Media
Filip Podjaski, Daniel Weber, Siyuan Zhang +9
The rational design of hydrogen evolution reaction (HER) electrocatalysts which are competitive with platinum is an outstanding challenge to make power-to-gas technologies economic…
Fabrication of Hollow AlAu2 Nanoparticles by Solid State Dewetting and Oxidation of Al on Sapphire Substrate
Nimrod Gazit, Gunther Richter, Amit Sharma +2
The Al-Au binary diffusion couple is a classic example of the system exhibiting Kirkendall voiding during interdiffusion. We demonstrate that this effect, which is a major reason f…
