Precision Synthesis of a Single Chain Polymorph of a 2D Solid within Single‐Walled Carbon Nanotubes

open access: yesAdvanced Materials, EarlyView.
The precise synthesis of 1D materials has enabled the discovery of physical properties only accessible in length scales close to the atomic scale. Herein, it is demonstrated that encapsulation within single‐walled carbon nanotubes with matching diameters leads to a stoichiometric quasi‐1D van der Waals polymorph of a 2D pnictogen chalcogenide, Sb2Te3 ...

New Perspectives on Semiconducting Conjugated Oligomers for Neuromodulation in Hydra vulgaris

open access: yesAdvanced Materials Interfaces, EarlyView.
Semiconducting organic compounds, thiophene‐based, modify the rhythmic electrical activity of the cnidarian Hydra vulgaris acting on specific neuronal circuits. The ETE‐S trimer also forms electronically conducting wires in the living tissues of the animal.

Strategic Direct Printing for High‐Performance and Uniform Organic Thin‐Film Transistor Arrays

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents a strategic direct‐printing approach to achieve high‐performance printed organic thin‐film transistor arrays. A 12 × 12 printed transistor array with high electrical performances is successfully demonstrated, achieving a saturation mobility of 0.9 cm2·V−¹·s−¹ and a relative standard deviation of 14.4%.

Dynamic Excitonic Beam Switching with Atomically‐Thin Binary Blazed Gratings

open access: yesAdvanced Optical Materials, EarlyView.
Two mirrored and interleaved blazed gratings are patterned into a monolayer WS2, contacted with gold electrodes inside an electrochemical cell. Applying a gate voltage to one of the grating electrode suppresses the exciton in that grating, enabling selective beam switching between diffractive orders.

Large Bidirectional Refractive Index Change in Silicon‐rich Nitride via Visible Light Trimming

open access: yesAdvanced Optical Materials, EarlyView.
Continuous‐wave visible light trimming of PECVD silicon‐rich nitride micro‐ring resonators enables precise, large bidirectional refractive index tuning. Resonance shifts as fine as 10 pm are achieved with a cost‐effective setup, demonstrating large red shifts of 49.1 nm and blue shifts of 10.6 nm.

Colossal Terahertz Emission with Ultrafast Tunability Based on Van der Waals Ferroelectric NbOI2

open access: yesAdvanced Optical Materials, EarlyView.
The widespread THz applications are hindered by the scarcity of efficient ultrafast THz sources with on‐demand fast modulation and easy on‐chip integration capability. Here the discovery of colossal THz emission is reported from a van der Waals (vdW) ferroelectric semiconductor NbOI2 and demonstrates the ultrafast coherent control of the THz emission ...

Efficient Low‐Voltage Phase Shifter with Inkjet‐Printed Liquid Crystal on a Silicon on Insulator Platform

open access: yesAdvanced Optical Materials, EarlyView.
Demonstration of an electro‐optic phase shifter fabricated by inkjet printing liquid crystal on an integrated silicon photonics chip surface. On a completed silicon photonics wafer (including modulators, detectors, and metallization), the back‐end‐of‐line stack is opened up to inkjet‐print liquid crystal. A phase shift of 6 for 2.7 V is obtained within

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

open access: yesAdvanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,
