From Photoalignment to Structured Light: Liquid Crystal Platforms for Beam Shaping and Complex Wavefronts

Advanced Functional Materials, EarlyView.
Photoaligned and photopatterned liquid crystal platforms provide programmable control of optical phase, polarization, and spin‐orbit interactions, enabling compact generation of structured light and complex wavefronts. This review highlights how tailored molecular orientations transform simple beams into designed optical fields, opening versatile ...

Effect of Optical Illumination on Bubble Nanodomains

Advanced Functional Materials, EarlyView.
Stable surface‐confined nanoscale bubble domains are created and manipulated in PMN‐PT single crystals. Under above‐bandgap illumination, these bubble nanodomains remain unchanged. However, upon illumination cessation, they rapidly expand to switch the entire crystal surface, due to the accumulation of a large reservoir of electrons at the crystal ...

Dielectric Spectroscopy of Non-Stoichiometric SrMnO₃ Thin Films

Inorganics
The dielectric properties of non-stoichiometric SrMnO3 (SMO) thin films grown by molecular beam epitaxy were systematically investigated. Especially, the effects of cation stoichiometry-induced diverse types and densities of defects on the dielectric ...

Mimicking Silent Synapse Recruitment: A SiOx/Cu‐Pancake Memristive Device For Analog Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Electroforming‐free TiN/SiOx/Cu/SiOx/TiN memristive devices exploit pancake‐like Cu nanoparticles embedded in a SiOx double layer to create a heterogeneous Schottky‐barrier landscape. Under bias, oxygen‐vacancy redistribution progressively lowers local barriers and recruits initially inactive Cu‐PC pathways into a parallel conduction ensemble, enabling

Growth and characterisation of thin films of CuCl and related materials [PDF]

, 2012
CuCl thin films grown on (100) Si by thermal evaporation are studied by means of low temperature photoluminescence (PL) and reflectance spectroscopies. Spatially and wavelength resolved room temperature cathodoluminescence (CL) imaging of the surface of ...

Interface Engineering via Sb2Te3 Deposition Enables High‐Performance SWCNT Film Thermoelectrics

Advanced Functional Materials, EarlyView.
SWCNTs are promising for flexible thermoelectrics but suffer from low performance. Here, cold‐pressed SWCNT films combined with deposited Sb2Te3 form engineered interfaces that enhance charge transport and energy filtering. The composite achieves a high power factor (25.82 µW cm−1 K−2) and delivers a power density of 3 mW cm−2 at ΔT = 40 K, with ...

Enhanced Tantalum Superconducting Resonator Performance via All‐Surface Organic Monolayer Passivation

Advanced Functional Materials, EarlyView.
The internal quality factor of tantalum superconducting resonators is significantly increased by ∼140% in the low photon regime by passivating their surfaces with a high‐quality alkene self‐assembled monolayer. Our methodology promises to enhance the performance of superconducting quantum circuits.
