Direct Visualization of Irreducible Ferrielectricity in Crystals
Kai Du, Lei Guo, Jin Peng +12
In solids, charge polarity can one-to-one correspond to spin polarity phenomenologically, e.g. ferroelectricity/ferromagnetism, antiferroelectricity/antiferromagnetism, and even di…
Thickness dependent properties in oxide heterostructures driven by structurally induced metal-oxygen hybridization variations
Zhaoliang Liao, Nicolas Gauquelin, Robert J. Green +16
Thickness driven electronic phase transitions are broadly observed in different types of functional perovskite heterostructures. However, uncertainty remains whether these effects…
Monitoring Galvanic Replacement Through Three-Dimensional Morphological and Chemical Mapping
Bart Goris, Lakshminarayana Polavarapu, Sara Bals +2
Galvanic replacement reactions on metal nanoparticles are often used for the preparation of hollow nanostructures with tunable porosity and chemical composition, leading to tailore…
Synthesis of a 3D network of Pt nanowires by atomic layer deposition on carbonaceous template
Shaoren Deng, Mert Kurttepeli, Stella Deheryan +6
The formation of a 3D network composed of free standing and interconnected Pt nanowires is achieved by a two-step method, consisting of conformal deposition of Pt by atomic layer d…
Three dimensional valency mapping in CeO nanocrystals
Bart Goris, Stuart Turner, Sara Bals +1
Using electron tomography in combination with spatially resolved electron energy-loss spectroscopy at high energy resolution, we are able to map the valency of the Ce ions in CeO$_…
Atomic resolution mapping of phonon excitations in STEM-EELS experiments
R. Egoavil, N. Gauquelin, G. T. Martinez +3
Atomically resolved electron energy-loss spectroscopy experiments are commonplace in modern aberrationcorrected transmission electron microscopes. Energy resolution has also been i…
