ABSTRACT:
A semiconductor capable of exhibiting an electron transfer effect in a high electric field is used as a Hall element. Application of a voltage large enough to give rise to an electron transfer effect to the current input electrodes of the Hall element brings about a decrease in the concentration of electrons contributing to the Hall effect occurring within the semiconductor, an increase in the Hall coefficient and a notable enhancement in the sensitivity of the Hall element.
