作者： Qiyu yanG Zheng-Dong LUO Fei xiaO Junpeng ZHANG Dawei ZHANG Dongxin TAN Xuetao GAN yan LIU Zhufei CHU Yinshui xia Genquan HAN Hangzhou Institute of Technology Xidian University State Key Discipline Laboratory of Wide Band Gap Semiconductor Technology School of MicroelectronicsXidian University School of Artificial Intelligence Xidian University School of Materials Science and Engineering University of New South Wales (UNSW) Sydney ARC Centre of Excellence in Future Low-Energy Electronics Technologies (FLEET) University of New South Wales (UNSW) Sydney Key Laboratory of Light Field Manipulation and Information Acquisition Ministry of Industry and Information Technologyand Shaanxi Key Laboratory of Optical Information TechnologySchool of Physical Science and TechnologyNorthwestern Polytechnical University Faculty of Electrical Engineering and Computer Science Ningbo University

Driven by the explosive development of data-centric computation applications, it is becoming urgent to develop in-memory computing devices that are beyond the von Neumann architecture with an arrangement of separated logic and memory components. The transistor-type solid-state non-volatile memories,such as ferroelectric field-effect transistors(Fe FETs), have long been regarded as a competitive candidate for future in-memory computing architectures. However, the density scaling towards high-density arrays would require advanced Fe FETs with reduced footprints, which remains a great challenge so far. Here, a vertical-transport(VT) Fe FET that flips the charge transport channel perpendicular to the substrate plane is proposed, in which a ferroelectric gate and a van der Waals(vd W) heterojunction channel are vertically integrated, effectively reducing the device footprints. The proposed VT-Fe FET shows not only the robust binary non-volatile memory states but also several key synaptic functionalities at the device level. An artificial neural network with supervised learning was simulated based on the device conductance switching properties,showing excellent classification accuracy for the MNIST handwritten digits. These findings suggest that the proposed VT-Fe FET could offer a new solution for future non-volatile memories as well as more advanced neuromorphic systems.

The facile construction of nanoscale NbH_(x)supported by Ti_(3)C_(2)(NbH_(x)@Ti_(3)C_(2))was achieved using facile ball milling strategy to improve the hydrogen desorption kinetics and reversibility of magnesium borohydride(Mg(BH_(4))_(2)).The doping of 30 wt%NbH_(x)@Ti_(3)C_(2)catalyst reduced the onset dehydrogenation temperature of Mg(BH_(4))_(2)to 71.2℃.Additionally,the Mg(BH_(4))_(2)+30NbH_(x)@Ti_(3)C_(2)composite achieved remarkable hydrogen release of over 9.2 wt%at a temperature as low as 230℃,indicating unexpected dehydrogenation ***,the reversibility of NbH_(x)@Ti_(3)C_(2)doped Mg(BH_(4))_(2)was retained to more than 4.2 wt%after four cycles,which was increased by 68%compared to that of undoped Mg(BH_(4))_(2).The strong catalysis of NbH_(x)@Ti_(3)C_(2)catalyst could be attributed to the synergistic effect of NbH_(x)and Ti_(3)C_(2)in hydrogen spillover and ***_(x)acted as a"hydrogen pump"for effective hydrogen spillover,while Ti_(3)C_(2)created numerous diffusion channels for hydrogen dissolution and provided the active catalytic site to facilitate the re/dehydrogenation of Mg(BH_(4))_(2).
