Model 8404 AC/DC Field Hall Measurement System
Because of their low charge carrier mobilities and the high temperatures needed to characterize high power devices, many contemporary semiconductor and electronic materials have electronic properties that are difficult to measure. This can be problematic as these materials are being used more and more in applications involving photovoltaic (solar cell) materials, thermoelectric materials, new display technologies, high power devices, and in organic electronics.
The Model 8404 AC/DC Field Hall Measurement System was designed to measure mobilities in semiconductor and electronic materials 10-3 to 106 cm2/V s. The system also has an AC field hall measurement option that is able to measure mobilities down to 0.001 cm2/V s. The AC option makes it possible to easily characterize photovoltaic and thermoelectric materials, and to reliably measure the Hall effect in low mobility organic electronics. Organic electronics are the basis for printable and flexible electronic devices, as well as organic light emitting diodes and organic solar cell materials.
This provides a solution to the problem of extracting the small Hall voltage from the background noise semiconductor and electronic materials typically produce, allowing these materials to be easily measured.
The Model 8404 AC/DC Field Hall Measurement System provides a range of Hall measurements on van der Pauw samples. The standard system is capable of DC field measurements and has a resistance range from 0.5 mΩ to 10 MΩ. AC field capability tops the list of an assortment of options including variable temperature assemblies, high and low resistance, and optical access. These add-ons broaden your measurement opportunities and simplify experimental processes. The Model 8404 HMS provides a robust platform to which you can add new features as your material measurement needs evolve.
