Ionized acceptors

WebThe concentration of ionized acceptors and donors in a semiconductor are NA, ND, respectively. If NA > ND and n1 is the intrinsic concentration, the position of the Fermi level with respect to the intrinsic level depends on (a) NA - ND (b) NA + ND (c) NA-ND/ni^2 (d) n1 Holooly.com Subscribe $4.99/month WebWithin the depletion approximation we suppose p n 0 in the depletion region. Another assumption is that all acceptors are ionized. The charge increment dQ s appears due to a slight increase in the space charge region width. The term dN A/dV was neglected, assuming NA does not depend on voltage.

T. The electrostatic potential at 0+ does not increase further and the depletion region stops expanding. How wide are the accumulation and strong inversion layers?

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:
