Although the Hall effect itself does not directly involve the reaction of chemical elements, the conductive properties of semiconductor materials are closely related to their internal electronic structure and chemical element composition. The conductivity of semiconductor materials is between that of conductors and insulators, and their electronic structure makes them very sensitive to changes in magnetic fields, which can produce a significant Hall effect. Therefore, it can be said that the conductivity of semiconductor materials used in Hall sensors is determined by their chemical element composition and electronic structure.
