WebThe ionized acceptors are those which cannot move. Now, when we increase the Gate voltage equal to Threshold voltage (Vth), still more electrons are created beneath the oxide which cannot have no holes to recombine since there is a depletion region barrier (created by step 1) to reach the next hole.
WebThis means that all of the acceptors and donors will be ionized, since there are equal numbers of electrons and holes available to fill the impurity energy levels. Therefore, the total number of ionized impurities will be: N ion = N A + N D = N A + n i 2 N A We can plug in the values for n i and N D from above:
