名称 简介

薄膜外延与器件集成

背景:随着传统硅基器件尺寸逼近物理极限,集成电路面临性能提升受限、功耗激增、器件间互连瓶颈等问题。异质外延生长技术可以在原子级控制下,将性能互补的异质半导体材料集成在同一衬底上,构建出新型异质结结构,有效优化电子、光子、声子等行为,从而实现高迁移率、高频率、低功耗等性能突破,助力新一代高性能器件发展。

研究:本团队采用ALD、PLD、MOCVD技术实现钙钛矿氧化物、铪锆氧铁电薄膜等新型材料的外延生长与物性调控,通过调控薄膜应变、氧空位、界面特性等,获得优异的电学、光学和铁电性能,并以此为基础开发新型的功能性器件。

神经形态器件及类脑感知

背景:神经形态器件及类脑感知系统的研究旨在模拟人脑中神经元与突触的工作机制,以实现高效、低功耗的信息处理与感知功能。该领域融合材料科学、微电子技术与神经科学,能够突破传统冯·诺依曼架构在带宽、功耗和处理效率方面的瓶颈,为构建具备学习能力、自主感知和智能决策的新型计算系统奠定基础,在智能传感、边缘计算、医疗康复及下一代人工智能等方面具有广泛的应用前景和重要的战略意义。

研究:本团队基于材料制备方面的优势,以铁电材料、钙钛矿材料和二维材料等材料体系为基体,开发面向存内计算、视觉感知和神经形态计算的新型器件结构,重点聚焦于忆阻器、光电感知器件及铁电可重构晶体管等方向。团队通过构建异质集成结构、精控界面与缺陷态工程,有效调控器件的电学与光电响应行为,旨在实现高密度存储-计算融合、高灵敏多模态感知以及低功耗可重构逻辑功能等关键性能,为类脑智能芯片和新型计算架构提供器件层的基础支撑。

柔性器件设计与集成

背景:柔性器件作为新一代电子技术的重要发展方向,因其轻薄、可弯曲、可拉伸等特性,打破了传统刚性器件在形态与应用场景上的限制,推动了电子器件向可穿戴化、植入化、可集成化发展。其研究不仅有助于构建更贴合人体、舒适度高的智能设备,还在健康监测、智能医疗、软体机器人、智能制造等领域展现出广阔的应用前景。

研究:本团队主要通过两种策略实现柔性感知系统的设计:1)基于水凝胶、聚合物和纳米纤维等柔性材料体系构筑具有多模态(压力、温度、湿度等)感知能力的传感器件,并实现其在医疗健康、运动监测、人机交互等领域的应用;2)基于机械剥离、磁控溅射和旋涂工艺等技术手段实现铁电材料、二维材料和半导体材料在柔性衬底上的有效制备,并以此为基础构建柔性的存储、计算和逻辑器件。
