Interface Effects in Ultrathin Silicon on Insulator Films

Advanced Functional Materials, EarlyView.
This work establishes a systematic framework to discriminate how bulk and interface phenomena affect charge transport in ultrathin P‐doped silicon‐on‐insulator (SOI) films. For Si films below 15 nm, electrical characterization demonstrates that interface states drive charge transport, shifting the metal‐insulator transition (MIT) critical dopant ...

Nano‐Scale Characterization of Impurities Segregation in Solid Oxide Electrolysis Cells

Advanced Functional Materials, EarlyView.
Cathodic polarization induces impurity segregation in Ni, forming an amorphous Na─Al─Si─O amorphous phase at grain boundaries. Under ultralow oxygen partial pressure, multiple elements dissolve, migrate, and reoxidize within the metal. A patterned model system provides direct nanoscale evidence, clarifying the mechanism of polarization‐driven impurity ...

Single crystal functional oxides on silicon

Nature Communications, 2016
Synthesis of single-crystal complex-oxide films directly on silicon is difficult due to differing interfacial chemistry. Here, the authors demonstrate room-temperature integration of single-crystal lead zirconate titanate on to silicon to act as a gate ...

Submicron Metasurface Reconfigured Multiband Smart Windows

Advanced Functional Materials, EarlyView.
This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

All‐Solution‐Processed HgTe Quantum Dot Photodetectors for Extended Short‐Wavelength Infrared Range Enhanced by Plasmonic ITO Nanocrystals

Advanced Functional Materials, EarlyView.
All‐solution‐processed, low‐cost extended short‐wavelength infrared photodetectors are realized by coupling colloidal HgTe quantum dots to plasmonic In2O3:Sn,F nanocrystals. Localized surface plasmon resonances boost and spectrally tailor light absorption between 1500 and 3000 nm, enabling responsivities above 40 A W−1.

Microscopic Origin of Temperature‐Dependent Anisotropic Heat Transport in Ultrawide‐Bandgap Rutile GeO2

Advanced Functional Materials, EarlyView.
Rutile GeO2${\rm GeO}_{2}$ exhibits orientation‐dependent heat transport with temperature‐dependent anisotropy, showing higher cross‐plane thermal conductivity along [001] than along the equivalent in‐plane [100] and [010] directions. Temperature‐dependent TDTR measurements and first‐principles phonon calculations identify the microscopic phonon ...

A Multi-Objective Genetic Algorithm Approach for Silicon Photonics Design

Photonics
A multi-objective genetic algorithm approach is formulated to optimize the design of silicon-photonics complex circuits with contradicting performance metrics and no closed-form expression for the circuit performance.
