This talk will present our latest research adventures on 2D nanomaterials towards greater scientific understanding and advanced engineering applications. In particular, the talk will highlight our work on flexible electronics, zero-power devices, monolayer memory (atomristors), non-volatile RF switches, and wearable tattoo sensors. Non-volatile memory devices based on 2D materials are an application of defects and is a rapidly advancing field with rich physics that can be attributed to sulfur vacancies or metal diffusion. Atomistic modeling and atomic resolution imaging are contemporary tools under use to elucidate the memory phenomena. Likewise, from a practical point, electronic tattoos based on graphene have ushered a new material platform that has highly desirable practical attributes including optical transparency, mechanical imperceptibility, and is the thinnest conductive electrode sensor that can be integrated on skin for physiological measurements. Much of these research achievements have been published in nature, advanced materials, IEEE and ACS journals.
本讲座将介绍我们对二维纳米材料的最新研究历程，以期获得更深入的科学了解和先进的工程应用。特别是，这次演讲将重点介绍我们在柔性电子产品，零功率设备，单层存储器（原子电阻器），非易失性射频开关和可穿戴纹身传感器方面的工作。基于二维材料的非易失性存储设备是缺陷的一种应用，它是一个具有丰富物理特性的迅速发展的领域，可归因于硫空位或金属扩散。原子建模和原子分辨率成像是用于阐明记忆现象的当代工具。同样，从实际的角度出发，基于石墨烯的电子文身迎来了一个新的材料平台，该平台具有非常理想的实用属性，包括光学透明性，机械不透性，并且是可以集成在皮肤上进行生理测量的最薄的导电电极传感器。这些研究成果大部分已在自然，先进材料，IEEE和ACS系列期刊上发表。
