Boron is implanted into an n$-$type Si sample $($Nd $=1016/$cm $3),$

forming an abrupt junction of square cross section with area $=2$x$10-3$ cm $2.$ Assume that the

acceptor concentration in the p$-$type region is Na $=1019/$cm $3.$ Calculate Vo $,$ x no$,$ x po$,$ Q$+,$ and

E o for this junction at equilibrium $(3$
