For a junction in which the built-in voltage is 0.7V, what are the doping-concentrations in the two regions if:
a) they are equal,
b) they are in the ratio 10 to I. Mint: Use Eq.3.18 in the Text.] For each case, what is the width of the depletion region and the distance it extends each side of the junction? For a junction that is 30 tun by 50 gm in size, what is the magnitude of the uncovered charge on each side?
