High permittivity processed SrTiO3 for metamaterials applications at terahertz frequencies [PDF]
arXiv, 2017 High permittivity SrTiO3 for the realization of all-dielectric metamaterials operating at terahertz frequencies was fabricated. A comparison of different processing routes evidences that Spark Plasma Sintering is the most effective sintering process to yield high density ceramic with high permittivity. We compare this sintering process with two others.

Optical Control of Ferroelectric Imprint in BiFeO3
Advanced Functional Materials, EarlyView.Above‐bandgap irradiation at room temperature enables on‐demand optical control of defect‐driven built‐in electric fields in BiFeO₃ thin films, fabricated via scalable, chemical spray pyrolysis. These fields, otherwise “frozen‐in,” can cause severe device degradation, including non‐switchable polarization, dead layers near interfaces, and polarization ...

Advanced Functional Materials, EarlyView.This study evaluates the scalability of PQD GNC‐based LSCs for BIPV applications. Experimental data and Monte Carlo simulations predict performance up to 1 m2, achieving a peak power conversion efficiency of 3.17%. The results confirm the viability of these LSCs for energy‐efficient building applications.

Advanced Materials, EarlyView.This study proposes tribenzyl organic cation carried multidentate X‐type Lewis soft base to enhance adhesion and passivate defects simultaneously, aiming to achieve foldable and efficient perovskite nanocrystal‐based light‐emitting diodes. The resulting pure red F‐PeLEDs exhibit a recorded high EQE of 16.2% and robust mechanical properties to endure ...
