New Hall system offers flexibility for non-destructive testing of wafer-scale materials
Lake Shore Cryotronics has announced a new system to measure Hall mobility on wafer-scale materials as a function of temperature and field with the new Model 8425 system from Lake Shore Cryotronics.
The system offers DC fields to 2 T, resistances from 10 µΩ to 100 GΩ, and measurements over a range of temperatures (from 10 K to 400 K). In addition, it supports van der Pauw, Hall bar and gated Hall bar measurements and includes the latest in Lake Shore Hall measurement software capabilities for easy control of magnetic field, sample excitation, sample temperature and automated temperature loops. DC field measurement capabilities are the same as those for Lake Shore's other 8400 Series systems, including Hall voltage, IV curves, resistance and resistivity; and derived values include Hall coefficient, Hall mobility, carrier type, carrier density and magnetoresistance.
