Custom-designed low-dimensional quantum materials

这项提议着眼于快速增长的量子材料领域，更具体地说，是可以集成在硅光子平台上的量子光发射器，用于新一代光电子器件。硅光电子是一套技术，允许在集成平台上实现光子组件的小型化，并基于互补的金属氧化物半导体(CMOS)电子制造。在加拿大，使用电子束光刻和其他纳米加工步骤的快速成型技术发展迅速，但还需要更多的研究来改进量子材料制造过程中的离子注入制造步骤。在西方大学Goncharova教授的团队和澳大利亚Flinders大学的Sarah Harmer教授的合作项目Alliance International Catalyst Grant中，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(坦德离子加速器设备、西方大学的时间分辨光致发光，以及澳大利亚弗林德斯大学的光电子显微镜、角度分辨光电子能谱)将是实现该项目的关键。我们将研究两类量子发射体：第四族量子点(QD)和二维过渡金属硫化物半导体(2D TM)。这一国际合作将使他们能够获得最先进的表征工具，这些工具要么在加拿大不可用，要么在加拿大超额认购。在这个项目上接受培训的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，而且具备开发新的量子材料并将其集成到光子器件中的实践经验的学员。在这个项目中接受培训的其他学生可以在加拿大快速发展的量子领域寻求职业道路，包括工业、政府和学术界。

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.
