[vc_row][vc_column][vc_column_text]The Hall effect of semiconductor is much better than the metal. Many Hall element is come out of this phenomenon and widely used in automatic industry technology, testing technology and information processing , etc.Hall effect is the basic method to study the performance of semiconductor. Hall coefficient was measured based on Hall effect experiment, and can judge the conduction type,carrier concentration, carrier mobility and other important parameters of semiconductor materials.
