http://web.mit.edu/6.012/www/SP07-L2.pdf 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:
