With its ultra-wide bandgap, extremely high breakdown electric field, and exceptionally high thermal conductivity, diamond has emerged as an ideal substrate for high‑power, high‑frequency electronic devices. It can surpass the thermal‑dissipation and voltage‑withstand limits of conventional semiconductors and is already employed in high‑voltage switches and radiation‑hard detectors. In the optical domain, its broad transmittance spanning from the ultraviolet to the far infrared, combined with its exceptional hardness and strong Raman gain, makes it well suited for extreme‑environment infrared windows, high‑power laser output mirrors, and quantum color‑center light sources, thereby providing critical material support for next‑generation carbon‑based photonic chips and quantum technologies.
