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.
