Colloidal quantum dots (CQDs) represent a groundbreaking technology reshaping the landscape of commercial imaging and display solutions. This talk explores the rapid advancements in quantum-dot semiconductors, examining their unique properties and addressing the challenges they face in competing with state-of-the-art epitaxially grown compound semiconductors. Among the critical factors for commercial viability are material selection, suitable photodiode architecture, and scalable production methods. The presentation will address the important question: "How can we create a high-performance semiconductor from quantum dots?" Special attention will be given to manufacturing techniques, discussing the economic feasibility of scaling up to large wafer processing. Highlighting recent breakthroughs, we will showcase successful integrations of PbS QDs into compact, lightweight, low-power, and cost-effective imaging systems, emphasizing their potential as ideal candidates for next-generation shortwave infrared (SWIR) cameras and advanced imaging applications. The talk will also cover the challenges and opportunities in the commercialization process, including regulatory nuances, safety considerations, and strategies for reducing production costs.
