Conventional approaches for achieving diamond doping have significant disadvantages, including challenging growth profiles, limited environmental stability, and sub-optimal psuedo-vertical structures. Here, it is demonstrated that laser-written nanocarbon networks (NCNs) directly alleviate these issues, demonstrating the highly repeatable fabrication of robust and precise electrical architectures buried in diamond with proven stability over repeated temperature and voltage cycling. By varying the laser pulse repetition rate (PRR), a transition from Ohmic conductive to semiconductive/ambipolar behavior is achieved in the modified diamond. Furthermore, a proof-of-concept, all-carbon transistor architecture buried within the bulk diamond is presented, showcasing the potential for integrated device fabrication using the laser-writing process.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"16 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145153852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work proposes a synergistic strategy using an ultrathin alumina passivation layer combined with ultraviolet-assisted oxygen ambient rapid thermal annealing (UV-ORTA) to enable fully low-temperature sputtered high-performance amorphous indium gallium zinc oxide (a-IGZO) TFTs. The UV-ORTA process significantly improves the gate dielectric by reducing oxygen vacancies, increasing optical bandgap, and boosting capacitance density. The sputtered alumina layer effectively optimizes the dielectric/active layer interface, reducing defect density comparably to atomic layer deposition.

Electrical impedance tomography (EIT) enables such sensing by monitoring changes in conductivity, but its sensitivity is often highest near the electrodes, limiting performance for distant deformations. Existing strategies to address this limitation typically rely on introducing conductive material heterogeneities, such as anisotropic or patterned conductors, to redirect current flow. In this work, a fundamentally different approach is presented: utilizing a dielectric guide to manipulate the electric field within the conductive body. This method leverages widely used soft robotic materials, such as silicone, in a new role as a passive electric field guide, allowing reconfiguration of sensitivity distributions without embedding conductive components. Physical experiments with a conductive hydrogel cylinder show that the dielectric guide increases deformation sensing accuracy by 21%, reduces sensitivity to noise, and enables a reduction in the number of required EIT channels. This work establishes dielectric-based field manipulation as a novel design strategy for high-fidelity, low-interference proprioception in soft robotics.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"41 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work investigates the root causes of this issue and approaches to address them. Contrary to expectations, electron leakage toward the hole transport layer (HTL) is identified as a plays a primary role in limiting the efficiency of these devices. By using a multilayer ETL configuration that includes electron blocking interfaces, electron leakage is reduced, and higher EQE is achieved. Using this approach, a max EQE of ≈10% in green- and red-emitting QLEDs, the highest reported for a green QLED not utilizing a ZnO ETL and among the highest in the case of red QLEDs, has been demonstrated. Tests on electron-only devices as well as transient electroluminescence measurements point to a mechanism where the formation of electron space charges within the organic ETLs may be assisting hole injection in the quantum dot layer, thus helping to reduce leakage. The findings highlight the importance of layer interface engineering and leakage control for achieving higher EQE in QLEDs, and present strategies for the effective utilization of organic ETLs in them.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"28 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145134163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, strategies of realizing 2D-FETs are reviewed with sub-10 nm channels: i) Ultraprecise nanolithography, including electron-beam lithography, cold development, and block copolymers (BCP)-based directed self-assembly (DSA); ii) Nanogap formation, leveraging stress-induced cracking, grain-boundary widening, electromigration, carbon-nanotube masking, and shadow evaporation; iii) Vertical-channel architectures, where channel length is defined by dielectric thickness in metal–insulator–metal stacks or barristor structures; iv) Self-aligned isolation, employing ultrathin film oxidation, adhesion lithography, and heterostructure undercut processes to precisely define source-drain separations.

Herein, a laser lift-off-and-fuse (LLOF) process is proposed for transfer printing LM onto flexible substrates with a patterning resolution of hundreds of microns. Liquid metal nanoparticles (LM NPs) from the donor substrate are transferred and subsequently activated on the receiver substrate by laser pulses, resulting in uniform, conductive patterns with arbitrary designs. Specifically, the LLOF method involves two steps: a transferring step by high-fluence laser pulses and an in situ activation step by low-fluence laser pulses. The LLOF method is additive and free of thermal or chemical damage to soft substrates. It brings superior quality and processability for high-precision LM flexible devices on stretchable substrates. Multiphysics numerical simulations provide a detailed demonstration of the transient vaporization of LM NPs and reveal a dynamic vapor-driven droplet transfer process.
