Lab-Grown Synthetic Diamonds for High Performing Electronic Components in the Aerospace Sector

Abstract Recent advancements in low-pressure and low-temperature techniques for synthetic diamond fabrication, combined with progress in diamond doping and shaping, have enabled the electronic and electromechanical industries to access a broad range of materials specifically engineered to meet the rigorous demands of extraterrestrial and aerospace environments. This paper reviews the most significant integrations of low-pressure/low-temperature diamond into power-electronic devices, highlighting the state of the art, key advances, and current challenges toward the practical deployment of diamond-based power technologies for the aerospace sector applications. To ensure a thorough assessment of current research and international development initiatives, both scientific literature and international patents issued between 2014 and 2024 were analyzed, focusing on the geographical distribution of research and technological advances, patent activity, leading assignees, and funding entities. These indicators collectively demonstrate that, driven by the vision of next-generation aerospace electronic systems, the lab-grown diamond industry is experiencing substantial expansion, with the global aerospace and electronics sector valued at $15.2 billion in 2024, and expected to double to $30.8 billion by 2033 with a CAGR of 8.7%.
