L79/HCS – Hall Effect Measurement System

L79/HCS – Hall Effect Measurement System


On point

The L79/HCS System permits the characterization of semiconductor devices, it measures: mobility, resistivity, charge carrier concentration and Hall coefficient.

The roughed desktop setup offers different sample holders for various geometries and temperature requirements. An optional low temperature (LN2) attachment and a high temperature version up to 800°C ensure that all fields of application can be covered. Different permanent and electric magnets provide fixed or variable magnetic fields up to several Tesla.

The sample holder handle closes the measurement chamber vacuum tight. The measurement chamber is provided with a gas in and outlet, so measurements can be taken under controlled and changeable atmospheres. Different sample holders are available to take measurements from LN2 up to 800°C.

Optionally the actual magnetic field strength can be measured up to 150°C. During a measurement the sample does not have to be moved, as the two magnetic circuits assembled on a sledge can be moved to change the magnetic flux from positive to zero and negative.
