Plasma-aided nanofabrication: "plasma-building block" approach

, 2006
Unique features and benefits of the plasma-aided nanofabrication are considered by using the "plasma-building block" approach, which is based on plasma diagnostics and nanofilm characterization, cross-referenced by numerical simulation of generation and ...

Low‐Flicker‐Noise MoS2 Transistors Enabled by High‐κ Rare‐Earth Oxychlorides for Mixed‐Signal Electronics

Advanced Functional Materials, EarlyView.
Single‐crystalline LaOCl and GdOCl form atomically abrupt, Cl‐terminated interfaces with MoS2, enabling near‐ideal switching and suppressed flicker noise. Carrier‐number‐fluctuation analysis yields effective noise‐derived interface trap densities of 1.15–1.94 × 1010 cm−2 eV−1, approaching hexagonal boron nitride levels with high‐κ coupling.

Voltage Gated Ion Entry Into Two‐dimensional Angstrom‐Scale Channels

Advanced Functional Materials, EarlyView.
We demonstrate voltage‐gated ion transport through artificial Å‐scale slit channels (∼4 Å high) formed by van der Waals assembly of 2D materials. At low electric fields, ions are excluded while water permeates. Above a threshold voltage, nonlinear hysteretic conduction emerges, driven by ion dehydration and concentration‐dependent barriers, mimicking ...

Plow and Ridge Nanofabrication [PDF]

Small, 2013
Traditionally, scanning probe lithography tools are limited in resolution by the radius of curvature of the tip used. Herein, an approach is described for patterning the ridge of piled-up polymer that naturally occurs when a scanning probe is pressed against a soft surface.

Topically Delivered Treg‐Attracting Microparticle‐Hydrogel Composites Recruit Regulatory T Cells and Limit Cardiac Injury After Severe Ischemia

Advanced Healthcare Materials, EarlyView.
CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...
