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.

Rise in Stratospheric Water Vapor over the Past Two Decades: An Association with Tropical Atlantic Sea Surface Temperature

引用

Journal of Earth Science 2024年

作者： Yingli NIU Fei XIE Yan xia Na LIU Yuanyuan han Faculty of Geographical Science/School of Systems Science， Beijing Normal University Key Laboratory of Textile Chemical Engineering Auxiliaries， School of Environmental and Chemical Engineering， Xi'an Polytechnic University

Variations in stratospheric water vapor (SWV) impact not only dynamic and chemical stratospheric processes but also the rate of global warming by influencing the Earth’s energy budget. Multiple observations have indicated a significant increasing trend in SWV since 2005. Here， using both observations and idealized sensitivity experiments with a numerical model， we find that the warming in the tropical Atlantic is the main contributor to the increasing SWV trend since 2005. The warming of both the tropical Indian and Atlantic oceans elicits a Gill-Matsuno responses， and the tropopause warming caused by Atlantic warming is located over the Indo-Pacific warm pool， which tends to efficiently increase the SWV after 2005. The North Pacific warming， which weakens the Hadley cell， results in a reduction in the tropical tropopause height and consequential tropopause warming， especially over the warm pool， which also contributes to the SWV increase.
