Diamond Devices

We develop:

high-purity and specifically doped monocrystalline diamond layers for applications in quantum technologies, for example as single photon sources, high-resolution magnetic field probes, or for future power electronic devices based on diamond. We are also involved in the development, optimization and application of single-crystalline diamond wafers for optical and electronic applications.




Diamond quantum technologies

Diamond power electronics

Diamond-based quantum sensors detect magnetic and electric fields with a spatial resolution of a few nanometers. By combining different materials and designs, these solid-state quantum sensors are suitable for the sensitive detection of:

  • Atomic magnetic moments
  • Charges
  • Temperature
  • Pressure

They can be used for:

  • the determination of positions (navigation) 
  • Geodesy

As a representative of the group of semiconductor materials with large bandgaps, the material diamond with its interesting properties is ideal for high-voltage power devices that can be used at elevated temperatures.

The high breakdown voltage and outstanding thermal conductivity of diamond enable the development of devices that far exceed the performance of comparable silicon solutions.

Fraunhofer IAF utilizes these properties and uses single crystalline diamond for the development of novel electronic high-performance devices.
