 Hall effect Measurement System 霍尔效应测量系统（ ezHEMS ）

一、产品简介:

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.

霍尔效应测量系统为van der波夫和hallbar测量提供了一个创新的解决方案。它独特的设计允许用户测量在80k到500k之间的终分辨率和准确性。所有磁体移动和温度变化可以自动完成，不改变任何组件。ezHEMS支持数据记录和绘制宽范围材料属性；I -v曲线、电阻、电阻率、片电阻、磁阻、载流子浓度、霍尔迁移率、霍尔系数作为温度的函数。
