Freeform Fabrication of Layered Halide Perovskite Nanowire Heterojunctions

Advanced Materials, EarlyView.
‘All‐at‐once’ freeform fabrication of layered perovskite nanowire heterojunctions is realized by 3D printing employing meniscus‐guided crystallization. The integration of nanoscale additive manufacturing with layered halide perovskites will provide a versatile platform to freely design and realize highly stable perovskite‐based optoelectronic ...

Microwave bandpass filters using re-entrant resonators. [PDF]

, 2015
Design techniques for microwave bandpass filters using re-entrant resonators are presented. The key feature is that each re-entrant resonator in the filter generates a passband resonance and a finite frequency transmission zero, above the passband.

Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks

Advanced Materials, EarlyView.
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...
