Product Introduction of Hall Effect Tester:

The measurement of Hall effect is an important experimental method for studying semiconductors. By using the joint measurement of Hall coefficient and conductivity, the variable temperature Hall experiment instrument can be used to determine the conductivity type and carrier concentration of semiconductors. By measuring the changes in Hall coefficient and conductivity temperature, basic parameters such as the bandgap width, impurity ionization energy, and temperature coefficient of mobility of semiconductors can be determined.

The Hall effect tester adopts modern electronic technology and computer data acquisition system to measure the temperature dependent Hall coefficient and conductivity of Hall samples under weak field conditions, in order to determine various properties of semiconductor materials.
