ezHEMS™ Hall Effect Measurement System offers an innovative solution on Van der Pauw and Hall Bar measurements. Its unique design allows users to measure the samples between 80K to 500K with ultimate resolution and accuracy. All magnet moves and temperature changes can be done automatically without changing any components. ezHEMS™ enables data logging and plotting of wide range material properties; I-V curves, resistance, resistivity, sheet resistance, magnetoresistance, carrier concentration, Hall mobility, Hall coefficient as a function of temperature. ezHEMS Hall Effect Measurement System Configuration Supports Van der Pauw as well as Hall bar shaped samples Magnetic Field: φ70mm, minimum 0.6 Tesla (±5%) permanent magnet (Upgradable to 1 Tesla) Pt-100 resistance thermometer, 800K heater and PID temperature controller 77K-773K temperature range with ±0.2 K resolution. Entire temperature range in a single system. Computer control through USB interface Samples sizes from 5×5 mm to 20 mm x 20 mm & with thickness ≤6 mm Automated movement of magnets controlled by ezHEMS Control Software Fully automated measurement sequences The ezHEMS Measurement System Software Software Capabilities: Enables data logging and plotting of different measured quantities; I-V curve, resistance, resistivity, sheet resistance, magnetoresistance, carrier conc., Hall mobility, Hall coefficient etc. as a function of sample temperature (Full functionality of the software depends on the purchased options.) Provides the measured data in tabular form LabVIEW™ drivers Measurement Head Configurations Room Temperature (300K) Measurement Head 300K & 77K Measurement Head 77K-500K Measurement Head 300K-773K Measurement Head Light Intensity Dependent Measurement Module
