An Analytical Theory of Piezoresistive Effects in Hall Plates with Large Contacts

Figure 9

Rectangular device from Figure 6 with , for comparison of the analytical theory with a finite element simulation with COMSOL MULTIPHYSICS. The plots show the potential and current streamlines. (a) The left plot is for small mechanical stress difference (third line of Table 1); (b) the right plot is for large mechanical stress difference (last line of Table 1).
