Optical and dielectric properties of artificial diamond — •Theo Andreas Scherer — Karlsruhe Institute of Technology (KIT-IAM-AWP), Germany

Optical and dielectric properties are key features for the application of artificial diamond as windows for nuclear fusion reactor devices in heating and current drive of the plasma and diagnostics as well. The properties of diamond are unique in the sense of extraordinary values in comparison to other dielectric crystalline materials, like sapphire, spinel, garnet or other oxide materials. The influence of defects and microstructural effects will be discussed based on vibrational bands and RAMAN experiments. Doped diamond is also considered, especially related to electric conductivity experiments. Doped diamond can be used for detector applications.
