aNexus Hall effect systems 8400 Series

The aNexus Lake Shore 8400 Series offers versatility by supporting both DC and AC field Hall measurement techniques, catering to a wide spectrum of research needs. Equipped with fully integrated instrumentation, a magnet and power supply, and intuitive software, it significantly enhances research efficiency while ensuring reliable results.

Utilizing the AC field measurement feature, the system excels in analyzing materials with mobilities below 1 cm2/V ‍s, a category that poses challenges for conventional DC field Hall methods. This capability proves invaluable for studying modern semiconductor and electronic materials, including photovoltaic and thermoelectric materials, novel display technologies, and organic electronics.

The base system enables precise DC field measurements with a resistance range spanning from 0.5 mΩ to 10 MΩ. Key parameters such as Hall voltage, Hall coefficient, Hall mobility, and resistivity can be accurately determined. With optional enhancements, the system extends its capabilities to measure resistances down to 0.5 µΩ and up to 200 GΩ in DC fields. Moreover, it facilitates the analysis of carrier density and carrier mobility across varying temperatures, offering comprehensive insights into material properties.

For applications dependent on temperature variations, the 8400 Series offers versatile options to accommodate sample measurements ranging from 15 K to 1273 K. This capability is made possible through the integration of a closed-cycle refrigerator and high-temperature oven, allowing for precise control over temperature conditions. Additionally, for dedicated measurements at 77 K, an optional single-point LN2 body is available.

The 8400 Series HMS serves as a robust platform adaptable to your specific requirements, with the flexibility to incorporate new features as your material measurement needs evolve. A range of options, including variable temperature assemblies, high and low resistance configurations, and optical access, expand the scope of measurements possible and streamline experimental procedures.
