Growth and Characterisation of 2D Heterostructure Materials

虽然对2D材料的研究已经进行了很多年，但它们对新的颠覆性技术的影响和潜力仍然受到其增长以及缺乏可控和可再生接口和设备集成的问题的限制。这个项目将探索决定不同类别的二维材料的晶相，结构，缺陷，界面和异质集成控制的关键机制，包括：石墨烯、hBN和TMD。我们的目标是在选定的应用领域，如（生物）传感器，（光）电子和过滤新的集成功能的整体理解。该项目将把剑桥大学世界领先的增长专业知识与NPL独特的表征设施结合起来，特别是先进的二次离子质谱成像的新用途，以获得对杂质在成核和设备操作中的作用的前所未有的见解。

While research on 2D materials has been on-going for many years now, their impact and potentialfor new disruptive technologies remains limited by issues with their growth and lack of controlledand reproducible interfacing and device integration. This project will explore key mechanisms thatdictate crystal phase, structural, defect, interfacial and heterogeneous integration control for 2Dmaterials of different classes, incl. graphene, hBN and TMDs. We target a holistic understanding ofnovel integrated functionality in selected application areas such as (bio)sensors, (opto)electronicsand filtration. The project will bring together the world-leading growth expertise at the University ofCambridge with the unique characterisation facilities available at NPL, in particular the novel use ofadvanced secondary ion mass spectrometry imaging to gain unprecedented insights into the role of impurities in nucleation and device operation.
