Hi all - This is pulled from a past paper -
I'm only going to state the components that I find challenging of this problem - The rest will be attached in my solution set.
Essentially - given an intrinsic semiconductor comprised of group II-VI elements.
Upon doping with group V, what's the resultant type of doping achieved?
My assumption - As will be seen in my uploaded solutions - is that I can approximate an "average" semiconductor group of halfway between 2 and 6, and dope this with group 5.
Additionally - I'd like to clarify my answer for 7ciii vs 7a, as they ask similar questions, and receive very similar answers by very similar methods.
It feels deceptively trivial reaching the answer I did for 7ciii, given I'd just applied nearly identical methodology in 7a.
Taken from my annotated formula sheet - sorry about the hideousness
