Description
To the point
The Linseis HCS systems are mainly used to characterize semiconductor materials.
They can determine both the Hall constant and the specific resistance, as well as the charge carrier concentration and Hall mobilities of the samples derived from these.
The desktop base unit is available in different configurations, which can be equipped with different sample holders for different sample geometries and temperature requirements.
An optional low-temperature extension for the use of liquid nitrogen and a high-temperature version up to 800°C guarantee that all conceivable areas of application can be covered.
The built-in permanent and electromagnets provide fixed or variable magnetic fields of up to almost one Tesla.
The associated, comprehensive and Windows©-based software enables the uncomplicated recording of I-V and I-R curves as well as the measurement and evaluation of Hall mobility, electrical conductivity and charge carrier concentration.
The Linseis HCS systems can measure a wide variety of materials, including Si, SiGe, SiC, GaAs, InGaAs, InP, GaN (N type & P type) as well as metal layers, metal oxides and many more.

The magnet variants of the HCS
Electromagnetic option (HCS 10)
An electromagnet kit is available as an option for the permanent magnet.
The water-cooled electromagnet works in combination with a programmable power supply and a reversing switch.
The power supply can apply currents of up to 75 A, resulting in a variable magnetic field strength of up to +/-1 T.
Detailed view of the measuring body
Permament magnet option (HCS 1)
The HCS 1 is equipped with two magnetic circuits (neodymium), which are mounted on a movable carriage that can be optionally automated.
The system can be equipped with both a low-temperature and a high-temperature extension.
Halbach option (HCS 100)
The HCS 100 uses a magnet in Halbach configuration (permanent magnet in donut configuration) to apply either a DC or an AC magnetic field to the sample.
In combination with an alternating current supplied by a lock-in amplifier, this setup is a powerful tool for the investigation of challenging samples, as offsets and noise can be suppressed in most cases.

Application
Application example: Antimony Thin Film (150 nm Sb)
Antimony (Sb) is a semi-metal that is widely used in the field of thermoelectrics (in the form of alloys, e.g. Bi1-xSbx) and as a new application in the field of microelectronics. However, the largest applications for metallic antimony are lead-antimony plates in lead-acid batteries. The figure shows a complete characterization of a thin film produced by sputter deposition on SiO2/Si substrate with the Linseis HCS 1 (RT to 200°C option).
