Bidirectional Process Prediction in the Laser‐Induced‐Graphene Production Using Blackbox Deep Learning

Advanced Materials Technologies, EarlyView.
This study shows that a lightweight blackbox neural network provides a practical, cost‐effective solution for bidirectional process prediction in laser‐induced graphene (LIG) fabrication. Achieving high predictive performance with minimal overhead, the approach democratizes machine learning (ML) for resource‐limited environments.

Aluminum Oxynitride‐Engineered Transparent Aluminum Nitride Resistive Memory for Low‐Leakage Multilevel Switching in Micro‐LED Pixels

Advanced Materials Technologies, EarlyView.
An AlON interfacial layer is engineered within an AlN switching layer to enable transparent RRAM with four stable resistance states. The device achieves low‐voltage multilevel switching and a high HRS, allowing precise grayscale modulation and preventing light leakage in micro‐LEDs operated at VDD = 2.7 V.

Organic light-emitting diode

, 2011
An organic light emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current.

Understanding Interfacial Photoswitching Mechanisms in Atomically‐Thin TMD‐Spiropyran Hybrids

Advanced Materials Technologies, EarlyView.
Photochromic molecules can effectively modulate the optoelectronic properties of atomically thin transition metal dichalcogenide semiconductors. Spiropyran that switches its chemical configuration upon alternating UV and visible irradiation enables light‐programmable optoelectronic devices.

Exploring the Synergy of Combining BINAP and tCzBN Motifs Within Multi‐Resonant TADF Emitters to Enhance OLED Performance

Advanced Optical Materials, EarlyView.
This work presents two MR‐TADF emitters, BINAP‐BN1 and BINAP‐BN2, based on a BINAP core and differing numbers of tCzBN units. Both emitters show similar solution photophysics, but distinct behavior in doped films, where BINAP‐BN1 exhibits higher photoluminescence quantum yield and suppressed aggregation‐induced emission broadening compared to BINAP‐BN2.
