The instrument system is composed of electromagnet, electromagnet power supply, high-precision constant current source, high-precision voltmeter, Hall effect sample holder, standard sample, and system software. The CH-320 effector specially developed for this instrument system integrates a constant current source, a six-and-a-half-digit microvoltmeter and a complex switching relay-switch for Hall measurement into a whole, which greatly reduces the connection and operation of the experiment. CH-320 can be used as a constant current source and a microvoltmeter alone. It is used to measure important parameters such as carrier concentration, mobility, resistivity, and Hall coefficient of semiconductor materials. These parameters must be controlled in advance to understand the electrical characteristics of semiconductor materials. Therefore, the Hall effect test system is to understand and study semiconductor devices. And a necessary tool for the electrical properties of semiconductor materials. The experimental results are automatically calculated by the software, and the Bulk Carrier Concentration, Sheet Carrier Concentration, Mobility, Resistivity, Hall Coefficient (Hall) can be obtained at the same time. Coefficient), magnetoresistance (Magnetoresistance) and so on.
