L79/HCS – Hall Effect Measurement System

Characterization of semiconductor devices


On point

The Linseis HCS System allows the characterization of semiconductor devices. It measures: Hall Constant, Hall Mobility, Sheet Resistance, Resistivity, Conductivity and Charge Carrier Concentration.

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. Either a permanent or a water cooled electromagnet provide fixed or variable magnetic fields with a maximum flux density of +/- 1 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.

During a measurement the two magnetic circuits, assembled on a sledge, can be moved to change the magnetic flux from positive to zero and negative.
