MoS2 Memristors Made by Liquid–Liquid Interface Assembly and Ultraprecise Metal Printing

Advanced Electronic Materials, EarlyView.
A cleanroom‐free, fully additive fabrication route combines ultraprecise printed silver electrodes with Langmuir–Schaefer‐deposited bilayer MoS2 to realize ultralow‐power resistive switching devices. The resulting microscale memories exhibit low operating voltages, a large memory window, stable retention and endurance, demonstrating a scalable and cost‐

Free Charge Generation in Organic Photoconversion Devices–the Impact of Electrostatic Potentials

Advanced Energy Materials, EarlyView.
Free charge generation in organic photovoltaic and photodetector devices typically requires an external driving force to separate bound excitons formed upon photoexcitation. This review details how electrostatic potentials, arising from molecular charge distributions in organic semiconductors, can impact interfacial energetic landscapes and promote ...

Thermoradiative Diodes Using Black Phosphorus van der Waals Materials

Advanced Energy Materials, EarlyView.
We demonstrate thermoradiative diodes based on black phosphorus (bP${\rm bP}$)/molybdenum disulfide (MoS2$MoS_2$) van der Waals heterojunctions which generate power by exchanging photons with a colder environment. The bandgap of black phosphorus is well positioned to exchange photons with outer space through the mid‐wave atmospheric window.

Deep Learning–Based Extraction of Promising Material Groups and Common Features from High‐Dimensional Data: A Case of Optical Spectra of Inorganic Crystals

Advanced Intelligent Discovery, EarlyView.
We report a novel interpretation method for deep learning models based on feature extraction and clustering. Applying this method to an atomistic line graph neural network (ALIGNN) model trained on optical absorption spectra of 2,681 inorganic compounds obtained from first‐principles calculations, we successfully identify key factors underlying ...

Red Light‐Gated Charge Transfer Enables Trace Oxygen Response in Dye‐Sensitized TiO2–Carbon Nanotube Hybrids

Angewandte Chemie, EarlyView.
Light activation allows spatiotemporal control over materials, yet converting low‐energy red‐light excitation into chemically responsive electronic function remains challenging. Here we show that squaraine‐sensitized TiO2 domains embedded in single‐walled carbon nanotube networks generate a red‐light‐gated charge‐transfer state that reacts with O2 ...
