(Color online) Sketch of the semiconductor-metal hybrid structure used for simulation. The input current lead is labeled as and the two output current leads are labeled as and . The two voltage probes are marked as and . The red block represents the magnetic bit.
(Color online) Current density distribution in the semiconductor-metal hybrid device at different magnetic fields. (a) , (b) , and (c) . The color represents the strength of current density. The white color near the current leads means the current density is very high.
(Color online) Influence of magnetic field on the output currents.
(Color online) Relation between EMR and magnetic field at different current leads. The EMR values of traditional configuration are also included.
(Color online) Calculated output current as a function of bit position for different magnetic fields of bit. The magnetic bit moves longitudinally along the rectangular semiconducting bar (see Fig. 1). The dimensions of the magnetic bit are .
