Hall elements are by far the most widely used magnetic sensor. In general, higher mobility and thinner active region of semiconductor used, better device. While common field sensors Si-based sensors, devices made from III-V compounds tend to favor over that based on Si. However these more expensive difficult manufacture than Si hard be integrated with signal-processing circuits for extending function enforcing performance. this article we show graphene is intrinsically an ideal material which may harness remarkable properties graphene, i.e. extremely high carrier atomically thin body, create sensitivity, excellent linearity thermal stability.
