R&D for large area high quality freestanding diamond wafers

R&D for large area high quality freestanding diamond wafers suitable for high power laser window and high power microwave (Gyrotron) window, as well as for electronic applications.

3-5 inch (φ76-127mm) crack-free and high quality diamond films were prepared by optimizing deposition parameters

These microwave reactors are fully functional, and the process parameters for fabrication of large size, high quality freestanding diamond disks suitable for the use as optical,laser, and microwave windows have been optimized.
