Model 8404 AC/DC Hall Effect Measurement System

A number of contemporary electronic and semiconductor materials are being developed for applications that include thermoelectric and photovoltaic materials, organic electronics, new display technologies and high power devices. It is very tough to measure the electronic properties of these materials. Presently available DC field electronic transport property measurement systems cannot measure many of these materials because of their low charge carrier mobilities and the high temperatures required for characterization of high power devices.

The Model 8404 Hall effect measurement system (HMS), developed by Toyo and Lake Shore, offers an AC field Hall measurement option that can measure mobilities down to 0.001 cm2/Vs, enabling these materials to be measured easily.

Key Features

  • Mobilities from 10-3 to 106 cm2/V s
  • DC fields to 1.67 T and optional AC fields to 1.18 T
  • Resistances from 10 µΩ to 200 GΩ
  • Temperatures from 10 K to 1273 K
  • Wide range of Hall measurements on van der Pauw samples
  • Variable temperature assemblies, high and low resistance, and optical access
  • Robust platform to which new features can be added as material measurement needs evolve

Fields of Study and Research

The Model 8404 HMS integrates the best of both DC and AC field Hall measurement methodologies to enable a wide range of research applications, such as thermoelectrics and photovoltaics, and organic electronics. The HMS utility is configurable to meet specific needs, extended by the optional variable temperature modules and measurement platforms available.
