Research on new materials and devices with novel functionalities has been supporting the rapid economic growth of Canada and technological innovations in industries, such as semiconductor, in the last several decades. Two-dimensional (2D) crystal materials present a broad playground, where the interface effects and nanoscale confinements often lead to substantial modifications in their electronic and magnetic ground states. Notable examples of these 2D materials include graphene and transition metal chalcogenides (TMCs) such as topological insulators Bi2Se3. The proposed research program capitalizes on such high tunability of their properties of the 2D materials and their great potential for functional devices, with the goal of designing, inducing, and controlling new states in TMCs, perovskite oxides, and other novel 2D materials systems. Achieving materials systems that permit experimental realization of the emergent properties and support next-generation of electronic devices lies at the heart of this proposal. This program will unprecedentedly integrate molecular beam epitaxy (MBE) synthesis with nanostructure fabrication, and a wide range of characterization techniques to explore and control the emergent properties in new materials. This kind of integrated research capabilities is extremely rare in other institutes in Canada and internationally, due to the limit of research infrastructures. At UBC, we aim to build a world-leading research program that allows us to routinely design and study nanostructured materials with new forms of properties. The main equipment to conduct the proposed research is an integrated cluster system consisting of an oxide MBE, a TMC MBE, and an angel-resolved photoemission spectroscopy (ARPES). This state-of-the-art infrastructure will be the first of such at UBC, with less than five existing over the world, and give us unique capability to expand the research areas and to help Canada to lead in the development of cutting-edge materials.Stewart Blusson Quantum Matter Institute of UBC provides a platform for exciting interdisciplinary collaboration opportunities in condensed matter physics, nanoscience, and materials science for students at both the graduate and undergraduate levels and for post-doctorate fellows. Through the collaborations, they will be exposed to the state-of-the-art infrastructures and conduct forefront research. Highly qualified personnel (HQP) will gain not only the required knowledge and skills as an independent researcher, but also a better understanding of how a research program as such helps to shape our daily life through scientific and technological innovations. These qualities will prepare them to pursue and guarantee them a successful career in academia and in industries, with their leadership vision at a global level.

在过去的几十年中，对具有新功能的新材料和设备的研究一直在支持加拿大的快速经济增长以及诸如半导体等行业的技术创新。二维（2D）晶体材料呈现一个宽阔的操场，界面效应和纳米级约束通常会导致其电子和磁接地状态进行实质性修饰。这些2D材料的显着示例包括石墨烯和过渡金属硫化剂（TMC），例如拓扑绝缘子BI2SE3。拟议的研究计划利用了其2D材料的性能的高可调性以及其功能设备的巨大潜力，其目的是设计，诱导和控制TMCS，钙钛矿氧化物和其他新型2D材料系统的新状态。实现允许实现新兴特性和支持电子设备的下一代的材料系统是该提案的核心。该程序将前所未有地将分子束外延（MBE）的合成与纳米结构的制造整合在一起，并将广泛的表征技术探索和控制新材料中的新兴特性。由于研究基础设施的极限，这种综合研究能力在加拿大和国际的其他机构中极为罕见。在UBC，我们旨在建立一个世界领先的研究计划，使我们能够常规设计和研究具有新形式的属性的纳米结构材料。进行拟议研究的主要设备是由氧化物MBE，TMC MBE和天使分辨光发射光谱（ARPES）组成的集成集群系统。 This state-of-the-art infrastructure will be the first of such at UBC, with less than five existing over the world, and give us unique capability to expand the research areas and to help Canada to lead in the development of cutting-edge materials.Stewart Blusson Quantum Matter Institute of UBC provides a platform for exciting interdisciplinary collaboration opportunities in condensed matter physics, nanoscience, and materials science for students at both the graduate and undergraduate levels and for后者的研究员。通过合作，他们将接触到最先进的基础设施并进行前沿研究。高素质的人员（HQP）不仅将获得作为独立研究人员所需的知识和技能，而且还可以更好地了解研究计划如何通过科学和技术创新来帮助塑造我们的日常生活。 这些素质将使他们在全球领域的领导愿景中为他们追求并确保他们在学术界和行业中取得成功的职业生涯。
