Our understanding of how subtle quantum effects can control the macroscopic behaviour of materials in recent years is ushering in a new era in the development of new functional quantum materials. These new quantum materials and devices are expected to result in transformative quantum technologies for a variety of application fields ranging from computing, information and communication technologies to novel sensing platforms and advanced energy applications. Within this framework, one application of quantum materials is the design and development of new types of solid-state single photon emitters for advanced device applications such as in quantum light emitting diodes, quantum radiometer, quantum key distribution, biomedical imaging, and high-resolution biomarkers.In this regard, the objective of this proposal is to catalyse the development of new quantum materials for these applications via the synthesis of semiconductor nanocrystals using the newly available gas-phase cluster agglomeration (GPCA) technique. The GPCA technique offers significant potential for controlled synthesis and introduction of dopant ion species during nanocrystal growth, and thus enable the fabrication of Bragg cavity and quantum electrodynamic cavity devices.This international project, a collaboration between researchers at the University of Toronto and University of Manchester, is a confluence of fundamental expertise in unique dry chemistry nanoscale materials synthesis, advanced functional materials characterization, and device design and fabrication. The complementary expertise will serve to accelerate the development of quantum materials and devices and will accordingly advance Canada among the forefront nations developing this emerging field of quantum technologies.
