Cryoelectronic Characterization

Example of a specialized sample holder and an interdigital measurements structures for capacitive measurements of ferroelectric films

Various cryostats and measurement setups are available for the electronic and magnetic characterization of thin film samples. They are specially equipment for the characterization of ferroelectric, superconducting and magnetic films. The sample holders are designed in house and optimized for various measurements. All experiments are automated and can be operated in remote control.
