8.3.2 Field and Charge Distribution

Using the new simulator allows to take a closer look at the properties inside the device and verify the operating principle outlined in Section 7.2.1.

The gate voltage used for sensing was set to $V_\mathrm{g}=0V$. The applied peak values of the gate voltage pulses were $V_g=\pm1\mathrm{V}$. Fig. 8.19 and Fig. 8.21 show the space charge density and the current density in the ON state, Fig. 8.21 and Fig. 8.22 in the OFF state.
