This proposal focuses on the quickly growing field of quantum materials, more specifically quantum light emitters that can be integrated in silicon photonic platforms for new generation of photonics devices. Si photonics is a suite of technologies that allows for the miniaturization of photonic components on the integrated platform and is based on complementary metal-oxide-semiconductor (CMOS) electronics manufacturing. There is fast growth of rapid prototyping using electron beam lithography and other nanofabrication steps in Canada, yet additional research is required to improve upon the ion implantation fabrication steps in quantum materials fabrication processes. In this Alliance International Catalyst grant, a collaborative project between Prof. Goncharova's group at Western University and Prof. Sarah Harmer's group at Flinders University, Australia, we will utilize ion implantation to fabricate new quantum light emitters, and explore electronic and light emission properties of these novel materials. Research expertise, experience and unique instruments for fabrication and characterization (Tandetron Ion Accelerator facility, Time-resolved Photoluminescence at Western University, and Photoemission Electron Microscopy, Angle Resolved Photoemission Spectroscopy at Flinders University, Australia) will be critical to enable this project. Two classes of quantum emitters will be investigated: group IV quantum dots (QDs) and 2D transition metal sulfides semiconductors (2D TMS). This international collaboration will give them access to the state-of-the-art characterization tools, that are either not available, or oversubscribed in Canada. HQPs trained on this project will be become highly skilled workers in the fields of quantum technologies and scientific instrumentation. Future quantum technologies will rely on trainees who not only master fundamentals of quantum mechanics, but also equipped with knowledge of practical experience of developing new quantum materials and integrating them in photonic devices. Additional students trained in this project can pursue career pathways in Canada's rapidly developing quantum filed including industry, government, and academia.

该提案专注于快速增长的量子材料领域，更具体地说，量子光发射器可以集成在硅光子平台中，用于新一代光子器件。Si光子学是一套允许集成平台上光子元件小型化的技术，基于互补金属氧化物半导体（CMOS）电子制造。在加拿大，使用电子束光刻和其他纳米制造步骤的快速原型制作快速增长，但需要进行额外的研究来改进量子材料制造过程中的离子注入制造步骤。在这项Alliance International Catalyst赠款中，西方大学Goncharova教授小组和澳大利亚弗林德斯大学Sarah Harmer教授小组之间的合作项目，我们将利用离子注入来制造新的量子光发射器，并探索这些新型材料的电子和光发射特性。研究专业知识、经验和独特的制造和表征仪器（Tandetron离子加速器设施、西部大学的时间分辨光致发光和澳大利亚弗林德斯大学的光发射电子显微镜、角分辨光发射光谱）对实现该项目至关重要。两类量子发射体将被研究：IV族量子点（QD）和2D过渡金属硫化物半导体（2D TMS）。这种国际合作将使他们能够获得最先进的表征工具，这些工具在加拿大要么是不可用的，要么是超额订购的。在该项目中接受培训的HQP将成为量子技术和科学仪器领域的高技能工人。未来的量子技术将依赖于不仅掌握量子力学基础知识，而且具备开发新量子材料并将其集成到光子器件中的实践经验的学员。在该项目中培训的其他学生可以在加拿大快速发展的量子领域（包括工业，政府和学术界）寻求职业途径。
