The special ellipsoid shape of the plasma reactor facilitates the deposition of diamond on a large surface.
Scanning electron microscope image of a diamond tip.
The radar module from Fraunhofer IAF is based on indium gallium arsenide semiconductor technology. It is extremely light and compact thanks to its monolithically integrated construction, in which different components and functions are integrated into a single chip.
Amplifier module: The low-noise, high-sensitivity microwave amplifiers of the Fraunhofer IAF can already detect signals of only a few nanowatts. They are based on the semiconductor material indium-gallium-arsenide.
Scientists at the IAF are working with partners to develop high-voltage transistors based on the high-performance semiconductor gallium nitride for use in voltage transformers.
Miniaturized, broadband spectrally tunable quantum cascade laser with emission wavelengths in the mid-infrared range and high scanning frequency up to 1 kHz.
In electromobility, as many small and efficient systems as possible have to be installed in a small space. The voltage converter shown in the picture is based on 4 x 3 mm² GaN power ICs with integrated transistors, gate drivers, diodes as well as current and temperature sensors for condition monitoring.
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.
A research team at the Fraunhofer IAF (project »PiTrans« within the framework of the Fraunhofer Attract program) has been working for several years on the piezoelectric properties of ScAlN for use in high-frequency filters. The photo shows the test of such devices on a wafer.
In our application laboratory, we offer spectroscopic measurements with our fast tunable quantum cascade lasers (QCLs). This innovative technology is based on wavelengths in the mid- to the long-wave infrared range and identifies chemical substances far more reliably than comparable spectroscopic measurement techniques in the near infrared wavelength range.
Diamond measuring tip with built-in nitrogen vacancy centre. New quantum physical systems open up new possibilities for highly sensitive sensor technologies.
With our high - performance RF circuits based on innovative III-V semiconductor technologies, the data rate of future wireless links can be significantly increased. In the EIVE project, for example, they are used to provide certain frequency ranges for broadband satellite communications.
On our robotic-measuring station our scientists can carry out measurements for customers or partners. Both, high-frequency sensors and optical sensors can be attached to the robot. With our customized measurement setups, it is possible to inspect components from different angles and distances. The measuring station can be adapted according to the application scenario.
Devices using heterojunctions are being developed in order to improve performance. These have significant advantages over commonly used homojunction devices, particularly in the field of dark current and noise behavior.
