Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

open access: yesAdvanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Design of RF filter based on RF components [PDF]

open access: yes, 2008
Inductors, L, and capacitors, C, are among the most important circuit elements, especially for the radio frequency, RF, applications. Such applications of these components include frequency-tuning circuits, filters, mixers, and matching networks.

Aluminum nitride for heatspreading in RF IC’s

open access: yes, 2008
To reduce the electrothermal instabilities in silicon-on-glass high-frequency bipolar devices, the integration of thin-film aluminum nitride as a heatspreader is studied.

Unlocking Exceptional Strengthening in Aluminum Alloys via Interstitial Cottrell Atmosphere Formation

open access: yesAdvanced Functional Materials, EarlyView.
Cyclic unloading‐aging‐reloading micro‐tensile tests under various aging durations and temperatures, combined with comprehensive microstructural characterization reveal that the yield point phenomenon in Aluminum‐Carbon (Al‐C) thin films originates from Cottrell atmosphere formation.

A Molecular Shielding Strategy to Develop Low Protein Binding, Renal Clearable Pan‐Cancer Near‐Infrared Probes

open access: yesAdvanced Functional Materials, EarlyView.
A molecular shielding strategy to convert “protein‐sticky” and “non‐tumor specific” clinical ICG dye, into a “low protein binding” and “tumor‐targeting” dye with prolonged blood circulation and renal clearance is described. These shielded ICGs demonstrate strong tumor accumulation and optimal tissue clearance, resulting in high tumor‐to‐background ...

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

open access: yesAdvanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...
