1. The problem statement, all variables and given/known data Question 6. Germanium forms a substitutional solid solution with silicon. (a) Compute the number of germanium atoms per cubic centimetre for a Ge-Si alloy that contains 25 w/o Ge and 75 w/o Si. (b) If, instead, phosphorus is added to Si to dope the material n-type at a doping of 1018/cm3, determine both the w/o and a/o of P in the Si. I have no idea how to do this question, what the question wants me to do, or w/o and a/o even mean. Can anyone can please put me on the right track, or even a track for starters, as this stuff is completely new to me and I have no idea. Not even where to start. Any help much appreciated, I have callister 7ed. if anyone knows where to find it, in that book.
