However, the heat generation of the devices cannot be ignored under such high-power consumption, which affects their normal operation and decreases the lifetime, or even causes damage in severe cases. Copper is the most widely used heat conducting material in electronic devices, but further improvement of its thermal properties to match the demand is still a crucial challenge. Graphene with ultra-high theoretical thermal conductivity is an ideal material to be combined with copper to improve its thermal conductivity, but the introduced graphene/copper interfaces bring phonon/electron scattering, which limits the heat transfer. In this work, laminated graphene-copper composites (HP-GCCs) are prepared by a hot-pressing strategy, the graphene/copper interfaces can form a stress-induced phonon-electron coupling effect through controlling the graphene distribution, which can improve the phonon-electron transmission of the interfaces and thus improve its thermal conductivity. The HP-GCCs exhibit a high thermal conductivity of 440.60 W m−1·K−1, showing reduced temperature-rise and improved efficiency when applied to devices in the practical applications. The investigations of the optimized graphene distribution of the composites through analyzing the mechanism of interfacial heat conduction provide valuable guidance for optimizing the synthesis and properties of 2D materials/copper composites.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"11 16","pages":""},"PeriodicalIF":5.3,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aelm.202500133","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144910809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the electronic structures and excitonic optical properties of ferroelectric-based heterostructure Sc2CO2↓/WSe2 and Sc2CO2↑/WSe2 with different out-of-plane polarization directions have been investigated by the GW+BSE formalism. The findings show that out-of-plane polarization can realize the transition of heterostructure band alignment from Type I to Type II by regulating the band structure of the adsorbed layer WSe2, significantly enhancing carrier separation efficiency. More importantly, changing the out-of-plane polarization direction enables dynamic regulation of the bright-dark attributes of heterostructure exciton states, achieving an optically switchable mechanism analogous to binary ″0″ and ″1″. Additionally, out-of-plane polarization exhibits significant regulatory effects on the optical absorption characteristics and radiative lifetimes of excitons.

A major obstacle in this field is the physical realization of activation functions, due to the lack of analog f (FETs) that inherently exhibit the desired piecewise-linear transfer characteristics. Here, a novel strategy is presented for implementing the Rectified Linear Unit (ReLU) activation function by exploiting the high density of states (DOS) associated with van Hove singularities (vHs), induced by flat bands in a kagome semiconductor Nb3Cl8 FET. This vHs-enhanced DOS imparts pronounced piecewise-linear transfer behavior at low temperatures, effectively mimicking the ReLU function. To enable room-temperature operation, the origin of the hysteresis commonly observed in Nb3Cl8 FETs is identified and addressed. Temperature-dependent and time-resolved measurements attribute the hysteresis to charge trapping at the Nb3Cl8–substrate interface. By introducing a hexagonal boron nitride (h-BN) buffer layer, the hysteresis is successfully suppressed, achieving stable and highly linear transfer characteristics at room temperature. These results demonstrate the potential of vHs-engineered electronic states for the physical implementation of analog activation functions, offering a pathway toward compact, high-density, and energy-efficient hardware for analog deep learning accelerators.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"11 16","pages":""},"PeriodicalIF":5.3,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aelm.202500255","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144900774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, mobility in IGZO TFT is still underwhelming. Here, accurate modulation of the Indium (In) ratio via a plasma-enhanced atomic-layer deposition (PEALD) approach is investigated, together with a post-deposition annealing (PDA) process over multiple temperatures. Through detailed material characterization, it is elucidated that a high In ratio with PDA favorｓ more In─O bonding and reduction of defects state. While a higher PDA temperature results in a higher mobility, other electrical performance is degraded due to unwanted defects generation. Optimized IGZO (In (5): Ga (1): Zn (1)) TFT is obtained after a PDA of 350 °C with a significant enhancement in field-effect mobility (µFE) from 25.10 to 66.04 cm2 V·s−1. In addition, the TFT achieves other excellent electrical performance, including an Ion-off of 107, low subthreshold swing (SS) of 79.25 mV dec−1, and threshold voltage (VTH) of −0.39 V.

Electrolyte‐gated organic synaptic transistors (EGOSTs) have emerged as promising building blocks for such systems due to their ability to mimic synaptic behavior through ion–electronic coupling, analogous to biological synapses. This review highlights recent advances in EGOST‐based neuromorphic motor control systems, focusing on their operational mechanisms, biological synaptic plasticity characteristics, and integration with motor actuators. A biological perspective on motor control is provided, emphasizing the roles of synaptic transmission and plasticity. It is then examined how these functions are emulated in EGOSTs, including strategies for tuning device behavior through morphology control and incorporating intrinsic sensing capabilities within a single device. Applications are categorized across artificial muscle fibers, robotic manipulators, and neuromuscular prostheses, demonstrating the versatility of EGOSTs in enabling low‐power, adaptive, and biointegrated motion control. Finally, key challenges—such as material limitations, electrochemical stability, and system‐level integration are discussed—that must be addressed to transition from proof‐of‐concept demonstrations to real‐world applications. This review underscores the transformative potential of EGOST‐based neuromorphic platforms for future wearable robotics, neuroprosthetics, and bioinspired intelligent systems.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"17 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144901829","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}
