A simple structured tunable negative refractive index (n) metamaterial (TNIM) has been designed, fabricated and tested in a Q-band rectangular waveguide. The structure consists of one slab of single crystalline scandium-doped barium hexaferrite (Sc-BaM), aligned parallel to two rows of periodic copper wires. The magnetic field tunable passband is measured indicating the occurrence of negative n...

Zero-dimensional metal halide perovskites have captured intense research interest owing to their unique optoelectronic properties. Particularly, halides with the ns2 electronic configuration are of great high-temperature sensitivity photoluminescence, which could be applied remote optical thermometry (ROT). Herein, all-inorganic and lead-free perovskite Te4+-doped Cs2InCl5·H2O single crystals (...

In this paper, the design, fabrication and characterization of PMUTs for medical applications are discussed. Scandium (20% Sc/(Sc $+$ Al)) doped AlN is used as piezoelectric material. The process with a patterned layer developed. Sing...

The development of a stable catalyst with excellent catalytic performance for the oxygen evolution reaction (OER) in alkaline environments is key various electrochemical technologies. In this work, single-atom catalysts (SACs) systems which scandium (Sc), rare earth metal, different N/C coordination (ScNxC3−x@SACs and ScNxC4−x@SACs Sc) were systematically studied help density functional theory ...

Abstract While recent studies have revealed that chemical doping can enhance the photovoltaic (PV) response of ferroelectrics under light with photon energy ( hν ) lower than bandgap E g ), its impact above-bandgap illumination > is not fully understood. In this study, PV at Mn - doped BiFeO 3 (BFO) thin films a periodic stripe domain pattern investigated. The short-circuit photocurrent dens...

Sc:Ru:Fe:LiNbO3 crystals were grown from congruent melt by using the Czochralski method. A series of LiNbO3 (Li/Nb = 48.6/51.4) with 0.1 wt% RuO2, 0.06 Fe2O3 and various concentrations Sc203 prepared. RF1 RF4 refers to samples containing 0 mol% 3 Sc203, respectively. The photorefractive properties measured Kr+ laser (λ 476 nm blue light): ηs 75.7%, τw 11 s, M/# 19.52, S 2.85 cmJ−1, Γ 31.8 cm−1 ...
