5.3.2 Magnetic Field

Figure 5.8 shows how the drain currents are modified when a magnetic field is applied at 77 K. As in the 300 K analysis, the bias is as follows: the drains are set to 1.0 V, the gate is set to 4.95 V, and the source and substrate are set to 0.0 V. As it can be seen, there is no qualitative difference between Figures 5.3 and 5.8. As expected, at 77 K the differential current is higher than at 300 K case by almost a factor of 10 (see Figure 5.9).
