Synergetic contributions of chemical doping and epitaxial stress to polarization in ferroelectric HfO2 films

Título : Synergetic contributions of chemical doping and epitaxial stress to polarization in ferroelectric HfO2 films
Autores:

Tingfeng Song, Huan Tan, Anne-Claire Robert, Saúl Estandia, Jaume Gázquez, Florencio Sánchez, Ignasi Fina

Citation and DOI: Applied Materials Today, Volume 29, 2022, 101621, ISSN 2352-9407,
DOI: https://doi.org/10.1016/j.apmt.2022.101621.
PlumX: Synergetic contributions of chemical doping and epitaxial stress to polarization in ferroelectric HfO2 films
In this work, we report on the critical role of the substrate selection to determine the amount of the metastable orthorhombic ferroelectric phase in La doped HfO2 films. Films grown on LSMO with smaller cLSMO (larger in-plane lattice parameter ultimately determined by the substrate selection) show larger amount of orthorhombic phase. While comparing La doped films with films doped with Zr grown in the same conditions, it is observed that La doping results in larger remanent polarization.

Jahn-Teller states mixed by spin-orbit coupling in an electromagnetic field

Título : Jahn-Teller states mixed by spin-orbit coupling in an electromagnetic field
Autores: A. S. Miñarro and G. Herranz
Citation and DOI:

Phys. Rev. B 106, 165108 – Published 6 October 2022
DOI: https://doi.org/10.1103/PhysRevB.106.165108

PlumX: Jahn-Teller states mixed by spin-orbit coupling in an electromagnetic field
Spin-orbit coupling plays a pivotal role in condensed matter physics. For instance, spin-orbit interactions affect the magnetization and transport dynamics in solids, while spins and momenta are locked in topological matter. Alternatively, spin-orbit entanglement may play an important role in exotic phenomena, like quantum spin liquids in 4d and 5d systems. An interesting question is how electronic states mixed by spin orbit coupling interact with electromagnetic fields, which may hold potential to tune their properties and reveal interesting physics.

PlumX: Chemical Solution Deposition of Insulating Yttria Nanolayers as Current Flow Diverter in Superconducting GdBa2Cu3O7−δ Coated Conductors
The primary benefit of a metallic stabilization/shunt in high temperature superconductor (HTS) coated conductors (CCs) is to prevent joule heating damage by providing an alternative path for the current flow during the HTS normal state transition (i.e., quench). However, the shunt presence in combination with unavoidable fluctuations in the critical current (Ic) of the HTS film can develop a localized quench along the CC’s length if the operational current is kept close to Ic. This scenario, also known as the hot-spot regime, can lead to the rupture of the CC if the local quench does not propagate fast enough.

PlumX: High-harmonic spectroscopy of quantum phase transitions in a high-Tc superconductor
We report on the nonlinear optical signatures of quantum phase transitions in the high-temperature superconductor YBCO, observed through high harmonic generation. While the linear optical response of the material is largely unchanged when cooling across the phase transitions, the nonlinear optical response sensitively imprints two critical points, one at the critical temperature of the cuprate with the exponential growth of the surface harmonic yield in the superconducting phase and another critical point, which marks the transition from strange metal to pseudogap phase.

How to switch from a poor PEDOT:X oxygen evolution reaction (OER) to a good one. A study on dual redox reversible PEDOT:metallacarborane

Título : How to switch from a poor PEDOT: X oxygen evolution reaction (OER) to a good one. A study on dual redox reversible PEDOT: metallacarborane

PlumX: How to switch from a poor PEDOT:X oxygen evolution reaction (OER) to a good one. A study on dual redox reversible PEDOT:metallacarborane
Over the years, extensive research has been carried out to optimize the oxygen evolution reaction (OER) by adopting different techniques as well as catalysts. Conducting organic polymers such as PEDOT have been employed to study the reaction but have failed to lower the over-potential for the reaction. Here we show electrochemically made, intimately blended, dual redox reversible materials incorporating PEDOT and metallacarboranes. The metallacarboranes act as doping agents but with tunable E1/2 potentials. The tunability of E1/2 allows the overlapping of the two redox potentials which subsequently leads to their synergy. The physico-chemical properties of the metallacarboranes fade and become integrated with PEDOT to form a dual redox reversible system. Therefore, the properties of the dopant are modified by the polymer.

Welcome to the ICMAB Annual Report 2021

2021 has been a year characterized by the "back-to-normal" life after the pandemic. 

The ICMAB has, step by step, returned to normality, but continuing with online and hybrid events and meetings, and with limitted capacity in the labs and offices for most of the year, and strict conditions to ensure the safety and health of all the ICMABers. 

However, our researchers and all our staff have worked hard to continue making this center one of the top centers in materials science research of the world.

Kinetic Control of Ultrafast Transient Liquid Assisted Growth of Solution-Derived YBa2Cu3O7-x Superconducting Films

PlumX: Kinetic Control of Ultrafast Transient Liquid Assisted Growth of Solution-Derived YBa2Cu3O7-x Superconducting Films
Transient liquid assisted growth (TLAG) is an ultrafast non-equilibrium growth process mainly governed by kinetic parameters, which are only accessible through fast in situ characterizations. In situ synchrotron X-ray diffraction (XRD) analysis and in situ electrical resistivity measurements are used to derive kinetic diagrams of YBa2Cu3O7−x (YBCO) superconducting films prepared via TLAG and to reveal the unique peculiarities of the process. In particular, diagrams for the phase evolution and the YBCO growth rates have been built for the two TLAG routes. It is shown that TLAG transient liquids can be obtained upon the melting of two barium cuprate phases (and not just one), differentiated by their copper oxidation state.
