Fastest Thickness Measurements with a Terahertz Time-Domain System Based on Electronically Controlled Optical Sampling

Applied Sciences, 2019
We apply a fast terahertz time-domain spectroscopy (TDS) system based on electronically controlled optical sampling (ECOPS) to contact-free thickness gauging.

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Handed Magnon Propagation in Easy‐Axis Antiferromagnetic α‐Fe2O3

Advanced Materials, EarlyView.
Coherent excitation and detection of handed magnons are achieved in the easy‐axis antiferromagnet α‐Fe2O3. An external magnetic field lifts the degeneracy between left‐ and right‐handed magnons without affecting their propagation velocity. The Dzyaloshinskii–Moriya interaction and anisotropy modulate their amplitude and damping, enabling intrinsic ...

Phase Engineering of Nanogold: Non‐Close Packed Square Planes in A′B′ Stacking with a 0.5 Å Channel

Advanced Materials, EarlyView.
Gold is well known to adopt the face‐centered‐cubic (fcc) structure. This work presents an unusual non‐close‐packed phase attained in a 40‐atom gold nanocluster, which is in contrast with the close‐packed fcc quasi‐isomer. The non‐compact structure exhibits exclusive square planes in a layer‐by‐layer stacking, hence, possessing a unique 0.5 Å channel ...

Trapped Fluorine Enables Thermally Stable Broadband Photodetection in Graphene/Fluorinated Graphene Heterostructure

Advanced Materials Technologies, EarlyView.
Fluorinated graphene has opened new opportunities for real‐world applications; however, its working and thermal stability are key issues for practical use. This study successfully demonstrates the stability of a fluorinated graphene‐based photodetector, achieved through a graphene, fluorinated graphene heterostructure (Gr/F‐Gr HS).
