The new Model 8407 Hall effect measurement system from Lake Shore Cryotronics (Westerville, OH) features a 7-inch magnet for measuring mobilities at the low end of the DC field measurement range, from 1 to 106 cm2/V s. Like Lake Shore’s existing Model 8404 with 4-inch magnet, it can be ordered with AC field measurement capabilities. Other features include:
• Capability of measuring materials with extremely low mobilities (down to 10-3/V s).
• Included software, which enables both van der Pauw and Hall bar measurements, measuring samples with gated Hall bars to account for gate bias, setting up loops with varying temperatures and gate voltages, performing time loops of measurements for longer unattended operation, and more.
