Highly Stable Epitaxially Crystallized Ferroelectric Hf0.5Zr0.5O2 Films

Written on .

Cooling conditions are critical in the crystallization of polycrystalline films of ferroelectric HfO2 because the energy of the HfO2 polymorphs is very sensitive to oxygen vacancies and because of the role of kinetics in the stabilization of the metastable orthorhombic phase. Here, we investigate the relevance of cooling conditions in the pulsed laser deposition of epitaxial Hf0.5Zr0.5O2 films. The orthorhombic phase crystallized in epitaxial Hf0.5Zr0.5O2 films does not change when highly reducing or oxidizing cooling conditions are used.

A sulfurization method for creating the buffer-layers current flow diverter architecture in REBa2Cu3O7 coated conductors

Written on .

The current flow diverter (CFD) is a known concept that has proven to effectively reduce the probability of destructive hot spots in REBa2Cu3O7 (REBCO; RE = rare earth) coated conductors (CCs) by boosting the normal zone propagation velocity. However, the implementation of the CFD concept requires additional steps in a fabrication process that is already complex and has struggled to find a simple reel-to-reel fabrication method.

  • PlumX: Roadmap on ferroelectric hafnia- and zirconia-based materials and devices
Ferroelectric hafnium and zirconium oxides have undergone rapid scientific development over the last decade, pushing them to the forefront of ultralow-power electronic systems. Maximizing the potential application in memory devices or supercapacitors of these materials requires a combined effort by the scientific community to address technical limitations, which still hinder their application.

Single─Not Double─3D-Aromaticity in an Oxidized Closo Icosahedral Dodecaiodo-Dodecaborate Cluster

Written on .

3D-aromatic molecules with (distorted) tetrahedral, octahedral, or spherical structures are much less common than typical 2D-aromatic species or even 2D-aromatic-in-3D systems. Closo boranes, [BnHn]2– (5 ≤ n ≤ 14) and carboranes are examples of compounds that are singly 3D-aromatic, and we now explore if there are species that are doubly 3D-aromatic.

Towards the Application of Purely Inorganic Icosahedral Boron Clusters in Emerging Nanomedicine

Written on .

Traditionally, drugs were obtained by extraction from medicinal plants, but more recently also by organic synthesis. Today, medicinal chemistry continues to focus on organic compounds and the majority of commercially available drugs are organic molecules, which can incorporate nitrogen, oxygen, and halogens, as well as carbon and hydrogen.

Domain distributions in tetragonal ferroelectric thin films probed by optical second harmonic generation

Written on .

Controlling the domain arrangement in a ferroelectric material is the key to accessing its functional properties. However, when a ferroelectric thin film is inserted into a multilayer device architecture, conventional characterization techniques provide limited access to the buried distribution of polar states.

First-ever wireless device developed to make magnetism appear in non-magnetic materials

Written on .

Researchers at the UAB and ICMAB-CSIC have succeeded in bringing wireless technology to the fundamental level of magnetic devices. The emergence and control of magnetic properties in cobalt nitride layers (initially non-magnetic) by voltage, without connecting the sample to electrical wiring, published in Nature Communications, represents a paradigm shift that can facilitate the creation of magnetic nanorobots for biomedicine and computing systems where basic information management processes do not require wiring.

Wireless magneto-ionics: voltage control of magnetism by bipolar electrochemistry

Modulation of magnetic properties through voltage-driven ion motion and redox processes, i.e., magneto-ionics, is a unique approach to control magnetism with electric field for low-power memory and spintronic applications. So far, magneto-ionics has been achieved through direct electrical connections to the actuated material.

N-Doped Octagon-Containing HBC as Redox and pH Chiroptical Switch in the NIR

Written on .

The optical and chiroptical properties of an aza-HBC-oct-[5]helicene have been studied and also modulated by means of protonation or oxidation. In both cases, the generated species shows a new absorption band in the NIR region that is not present in the neutral species. This result enables this N-doped nanographene to act both as optical and, remarkably, as chiroptical switch since both the CD and CPL can be modulated by external stimuli such as redox or pH changes.
