I. (25 points) Problem 5.9 of text. Assume complete ionization. II. (25 points) Problem 5.21 of text. III. (25 points) Problem 5.27 of text. Again assume complete ionization on both
sides. IV. (25 points) Problems 5.35 of text. Note that
e x e x

cosh( x ) 2 cosh( x ) e x e x & ctnh(x) sinh( x ) e x e x Also be careful of notation: Here xn is just x on the n-side and xn = 0 is the n-side
edge of the depletion region (not xn = xn,o as in figures in the text). And pn is the
equilibrium value of the minority hole concentration (what I have labeled pn-side,o
in my notes). 1 ...
