Abstract
A magnetometer or magnetic field sensor includes semiconductor material deposited laterally on an insulating substrate. The semiconductor material is alternating regions of n- and p-type silicon provided with two cathodes, an anode and a triggering node. Upon application of a triggering pulse to a switch on the sensor, a carrier domain is formed. In the presence of a magnetic field this carrier domain is deflected to one side thus causing an imbalance in the current collected at the two cathodes.
