Product Introduction
The measurement of Hall effect is an important experimental method for studying semiconductor properties. The joint measurement of Hall coefficient and conductivity can be used to determine the conductivity type of semiconductors Carrier concentration. By measuring the changes in Hall coefficient and conductivity with temperature, basic parameters such as the bandgap width, impurity ionization energy, and temperature coefficient of mobility of semiconductors can be determined. This instrument adopts modern electronic technology and computer data acquisition system to measure the variable temperature Hall coefficient and conductivity of Hall samples under weak field conditions, in order to determine various properties of semiconductor materials.
