Grant: Research Tools and Instruments

This proposal urgently seeks funding for the acquisition of a Nitrogen (N) Plasma Source, a critical addition to the existing material synthesis facility housed within the Quantum Materials and Devices Foundry (QMDF) at Quantum Materials Institute (QMI), UBC. The introduction of the N plasma source into our molecular beam epitaxy (MBE) system will enable the synthesis of previously unattainable nitride and oxynitride materials, which are renowned for their novel electronic and photonic properties, and hold immense potential for applications in both academic research and industrial technologies. These materials will serve as invaluable resources for multiple research groups across Canada, while fostering collaboration with leading institutions and companies. Additionally, the acquisition of this equipment supports equity, diversity, and inclusion (EDI) initiatives by enhancing the training of Highly Qualified Personnel (HQP). Core Objective: The primary goal of this proposal is to establish cutting-edge capabilities for development of nitride and oxynitride materials, which will offer a transformative approach in Canada's research community. Specifically, we aim to integrate both oxygen (O) and nitrogen (N) plasma sources within a single MBE chamber-a feat rarely attempted globally. Innovative Approach: The central innovation of this proposal lies in the ability to tailor the electronic structure of materials through anion site doping, specifically by controlling the incorporation of O and N atoms. This represents a paradigm shift from the conventional method of cation doping, unlocking new possibilities for unprecedented functionality. QMI combines both a world-leading theoretical group for N doping of oxides with experimental state-of-the-art MBE growth capabilities. Our research team, with extensive expertise in both experimental techniques and theoretical modeling at UBC, is fully equipped to lead this initiative. Impact on Canadian Quantum Research & Industry: The successful execution of this project will have far-reaching implications for the Canadian electronics, photonics, and quantum industries (Canada's National Quantum Strategy). Additionally, it will contribute to the LIGO project by developing nitrides for coatings designed to reduce mechanical noise in next-generation gravitational wave detectors. The proposed materials to be investigated include: 1.Enhanced superconductivity in nitrogen-doped oxides. 2.Wide bandgap semiconductors (e.g., GaN and Ga(O,N)) with applications in photonics and electronics. 3.N-doped magnetic perovskite oxides engineered to improve magnetic exchange through band hybridization. 4.Nitrides for LIGO coatings aimed at minimizing mechanical noise. These materials are poised to make substantial contributions to both academic research and industrial development. This funding is critical to seize the emerging opportunities in materials science and to further solidify Canada's leadership in this field.
