Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Photoluminescence of hexagonal boron nitride: effect of surface oxidation under UV-laser irradiation

, 2008
We report on the UV laser induced fluorescence of hexagonal boron nitride (h-BN) following nanosecond laser irradiation of the surface under vacuum and in different environments of nitrogen gas and ambient air.

Next‐Generation Aerogel Electrocatalysts for Oxygen Reduction Reaction

Small, EarlyView.
ABSTRACT Aerogel‐based electrocatalysts have become a groundbreaking class of materials for the oxygen reduction reaction (ORR), distinguished by their ultralight nature, pore networks, and outstanding electrical conductivity. Their interconnected three‐dimensional frameworks offer abundant active sites, efficient diffusion channels, and continuous ...

Stability of antiphase line defects in nanometer-sized boron-nitride cones

, 2004
We investigate the stability of boron nitride conical sheets of nanometer size, using first-principles calculations. Our results indicate that cones with an antiphase boundary (a line defect that contains either B-B or N-N bonds) can be more stable than ...

Single Cu Atom Sites on Co3O4 Activate Interfacial Oxygen for Enhanced Reactivity and Selective Gas Sensing at Low Temperature

Small, EarlyView.
Atomically dispersed Cu sites on Co3O4 nanoparticles establish well‐defined Cu–O–Co interfacial linkages that promote lattice oxygen activation at markedly reduced temperatures. This structural and electronic modulation yields over twenty‐fold higher low‐temperature formaldehyde sensing responses than CuO nanoparticle analogues, enabling selective and ...
