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.

过去几十年来，对具有新颖功能的新材料和设备的研究一直支持加拿大的快速经济增长和半导体等行业的技术创新。二维 (2D) 晶体材料提供了广阔的应用领域，其中界面效应和纳米级限制通常会导致其电子和磁性基态发生重大变化。这些二维材料的著名例子包括石墨烯和过渡金属硫属化物 (TMC)，例如拓扑绝缘体 Bi2Se3。拟议的研究计划利用了二维材料特性的高度可调性及其在功能器件方面的巨大潜力，目标是设计、诱导和控制TMC、钙钛矿氧化物和其他新型二维材料系统的新状态。该提案的核心是实现允许实验实现新兴特性并支持下一代电子设备的材料系统。该计划将前所未有地将分子束外延（MBE）合成与纳米结构制造以及广泛的表征技术相结合，以探索和控制新材料的新兴特性。由于研究基础设施的限制，这种综合研究能力在加拿大乃至国际其他机构中极为罕见。在 UBC，我们的目标是建立一个世界领先的研究项目，使我们能够定期设计和研究具有新特性的纳米结构材料。进行本研究的主要设备是由氧化物MBE、TMC MBE和天使分辨光电子能谱（ARPES）组成的集成簇系统。这种最先进的基础设施将是 UBC 的第一个此类基础设施，全球现有的设施不到五个，并赋予我们独特的能力来扩展研究领域并帮助加拿大在尖端技术的发展中处于领先地位。 UBC 的斯图尔特·布鲁森量子物质研究所为研究生和本科生以及博士后研究员提供了一个平台，为凝聚态物理、纳米科学和材料科学领域的令人兴奋的跨学科合作机会。通过合作，他们将接触最先进的基础设施并进行前沿研究。高素质人员（HQP）不仅将获得作为独立研究人员所需的知识和技能，还将更好地理解研究项目如何通过科技创新帮助塑造我们的日常生活。 这些品质将为他们在学术界和工业界追求并保证他们的职业生涯取得成功做好准备，并具有全球范围内的领导愿景。
