The importance of the Hall measurement is supported by the need to determine accurately carrier density, electrical resistivity and the mobility of carriers in semiconductors for thin film solar cells, LEDs and TCO layers. The system we offer is an AC system, providing alter-nating (AC) magnetic field (Max. field intensity of 1 T (peak to peak)) and a unique technol-ogy for noise reduction (Min. measurable Hall voltage 10 nV), for characterization of high resistance layered semiconductors (Max. surface resistance of sample 10 GΩ), e.g. CIGS, and organic materials. If you wish to use an accurate Hall effect measurement of high resistivity films by AC magnetic field, we suggest to try our hall effect system.
We can provide sample test before you buy.
