Someone explain to me how a PNP junction work (1 Viewer)

Well all I can say is that I don't understand them too, and I've been bugging my teacher about it since forever. And his answer is that he doesn't understand it himself and that it's not in the syllabus. So I guess you don't have to know it for the hsc.
The only thing I know about them is that some how if you put in a small current on one side, you "create" a larger current on the other side. My theory is that it's sorta like a transformer.

oh i hate this aswell!
But i know its got somthing to do with 'doping'. You take an element from coloum 4, and dope it with coloum 5.
Also, with semiconductors, silcon is used over the other one (cant remember name) because it is more abundant (it can be extracted more easily, and hence, more cheaply) and silicon creates an oxide insulator (??) when it is heated up. I guess this is why we have em in our computers (so it doesnt cook up)
