Hall Effect Devices

After a short introduction to the operating principle and the basic characteristics of Hall devices, the most interesting recent advances in the field are reviewed. They include: better understanding of the influence of device geometry on sensor characteristics; results of research into parasitic and second-order effects, such as the piezo-Hall effect, non-linearity effects and surface effects, the last affecting device sensitivity, 1/f noise and offset; new designs and technologies, yielding buried Hall devices, vertical Hall devices and two-dimensional electron gas Hall devices; and new electronic methods for the improvement of sensor characteristics, such as correction of non-linearity effects and offset reduction.
