Assume complete ionization and electron and hole mobilities are 3900 cm2/V⋅sec and 1900 cm2/V⋅sec. The applied electric field is E = 50 V/cm. - Solution Since N a > N d, the semiconductor is p-type and the majority carrier hole concentration,

In the weak inversion, the minority carrier concentration is small, but not zero. Fig. 5 shows the variation of minority carrier concentration along the length of the channel for an n-channel MOSFET biased in the weak inversion region. Let us consider that the source of the n-channel MOSFET is grounded, , and the drain to source voltage V.

-3)€ 1.83E19€ Note: at equilibrium, n = p ≡ n i where n i is the intrinsic carrier concentration. For pure silicon, then n2 NN exp(E /kT) i = c V − G Thus n i = 9.6 109 cm-3 Similarly the Fermi level for the intrinsic silicon is, E i = E V +(E C − E V)/2+(1/2)kTln(N V / N C) Where we have used E i to indicate intrinsic Fermi level for Si.

Intrinsic Carrier Concentration Contains an insignificant concentration of impurity atoms Under the equilibrium conditions, for every electron is created, a hole is created also n = p = ni As temperature is increased, the number of broken bonds (carriers) increases
