Gate‐Dielectric Surface Engineering With Fluorinated Monolayers: Minimizing Contact Resistance and Nonidealities in OFETs

open access: yesAdvanced Electronic Materials, EarlyView.
Surface engineering of gate dielectrics with fluorinated self–assembled monolayers significantly improves the performance of organic field–effect transistors. In this study, Al2O3 functionalized with fluorinated phosphonic acids reduces contact resistance and hysteresis while achieving near‐zero threshold voltages, offering an alternative to ...

Optical Charge Trap Memory Based on Graphene/ZnO Heterostructures for Long‐Term Retention and Adaptive Learning

open access: yesAdvanced Electronic Materials, EarlyView.
A biocompatible graphene/ZnO optical charge trap memory (CTM) is reported with over 54 h retention, enabled by interfacial photodoping. Using transient absorption spectroscopy and electrical analysis, charge transfer quenching is elucidated and reveal that a large energy barrier at the interface is responsible for long‐term memory retention.

Environmental Stability and Electronic Properties of Individual Flakes of Ti2CTx MXene

open access: yesAdvanced Electronic Materials, EarlyView.
The paper presents a synthesis of large Ti2CTx MXene flakes with sizes reaching 40 µm and examines their environmental stability and electronic behavior. It demonstrates that monolayer flakes degrade rapidly in ambient conditions, leading to semiconducting‐like behavior with low conductivity and mobility. In contrast, multilayer flakes exhibit enhanced

Reversible and Controllable Transition Between Filamentary and Interfacial Resistive Switching in HfO2‐Based Memristors

open access: yesAdvanced Electronic Materials, EarlyView.
5 nm HfO2 memristors exhibit a fully reversible, voltage‐controlled transition between filamentary and interfacial switching within the same device. At high voltages, a filament forms and dominates the conduction, whereas at lower voltages the device reversibly returns to interfacial mode without defect accumulation, implying a new reversible ...

Enhancement of the Photoelectric Performance of (6,5) Carbon Nanotubes via Construction of Type‐I Heterojunctions with Rhodamine B

open access: yesAdvanced Electronic Materials, EarlyView.
Single‐chirality (6,5) carbon nanotube (CNT) films, when integrated with RhB molecules to form Type I heterogeneous films, exhibit a more than twofold increase in photoluminescence efficiency and approximately one‐order‐of‐magnitude enhancement in photoelectric conversion efficiency compared to pristine (6,5) CNT films.

Highly Stabilized Ni‐Rich Cathodes Enabled by Artificially Reversing Naturally‐Formed Interface

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The application of Ni‐rich cathode materials is obstructed by interfacial and structural instability. This work proposes a facile and cost‐effective Al‐based vapor‐phase surface reaction strategy on Ni‐rich cathode to maintain its structural integrity from near‐surface to bulk.

Resolving Oxidative and Corrosive Calendar‐Aging via Electrolyte Engineering for Stable Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A weakly solvating ether solvent, 1,2‐dimethoxypropane (DMP), is proposed for use in localized high‐concentration electrolytes (LHCEs) for lithium metal batteries (LMBs). These DMP‐based LHCEs simultaneously suppress lithium metal corrosion and cathode degradation—two interrelated processes that accelerate calendar aging of LMBs.
