Diamond Devices

Fraunhofer IAF develops components and devices based on monocrystalline and polycrystalline diamond for use in electronic and optical devices as well as for novel applications in the field of quantum sensors.

This includes both the production of high-purity and specifically doped diamond layers using plasma CVD and the development of processes for further processing of the diamond.

Microsystems based on nano diamond

The Fraunhofer IAF develops novel micro-electro-mechanical systems (MEMS) based on diamond, aluminum nitride and aluminum scandium nitride, which preserve their outstanding opto-mechanical and electrical parameters in high temperature or radiation environments.

Diamond lenses for high power lasers

Our diamond lenses stay dimensionally stable due to their high thermal conductivity even at extreme temperatures, so that the focal point of the laser beam is not affected.

Our competences

From active devices to gemstones, we use a variety of processes to process diamond.

  • laser cutting
  • grinding and polishing
  • plasma etching
  • application of metallizations
  • homoepitaxy / heteroepitaxy
