Mentions: Conductivity control via minimally invasive anti-Frenkel defects in a functional oxide

Utilizing quantum effects in complex oxides, such as magnetism, multiferroicity and superconductivity, requires atomic-level control of the material’s structure and composition. In contrast, the continuous conductivity changes that enable artificial oxide-based synapses and multiconfigurational devices are driven by redox reactions and domain reconfigurations, which entail long-range ionic migration and changes in stoichiometry or structure.

On the Promotion of Catalytic Reactions by Surface Acoustic Waves

Written by icmabcsic on 25 September 2020.

Surface acoustic waves (SAW) allow to manipulate surfaces with potential applications in catalysis, sensor and nanotechnology. SAWs were shown to cause a strong increase in catalytic activity and selectivity in many oxidation and decomposition reactions on metallic and oxidic catalysts.

DOI: 10.1063/5.0017738

The growth window of epitaxial Hf_0.5Zr_0.5O₂ is established taking into account the main ferroelectric properties that films have to present simultaneously: high remanent polarization, low fatigue, and long retention.

Visualization of moiré superlattices

Written by icmabcsic on 18 September 2020.

Moiré superlattices in van der Waals heterostructures have given rise to a number of emergent electronic phenomena due to the interplay between atomic structure and electron correlations. Indeed, electrons in these structures have been recently found to exhibit a number of emergent properties that the individual layers themselves do not exhibit.

Photoinduced persistent electron accumulation and depletion in LaAlO3/SrTiO3 quantum wells

Written by icmabcsic on 23 June 2020.

Spike-timing dependent plasticity (STDP) is a fundamental concept in neurobiology. Briefly, the relative timing of two neuron spikes reinforces or weakens the synapse between them, so that events caused by another should trigger spikes in a particular time order.

High polarization, endurance and retention in sub-5 nm Hf0.5Zr0.5O2 films

Written by Jags on 05 June 2020.

Ferroelectric HfO₂ is a promising material for new memory devices, but significant improvement of important properties is necessary to reach applications. However, precedent literature shows that a dilemma between polarization, endurance and retention exists.
