An interesting guide to semi-conductors

http://britneyspears.ac/lasers.htm

For those who were a bit confused about the discussion of semi-conductors in lectures, the above link is a useful guide to their behaviour. Don't be alarmed by the URL, it is in fact a quite serious guide to semi-conductor physics, purportedly *written* by *Britney Spears*.

It has sections on the basics of semi-conductors, junctions, recombination and the other topics we touched on. I found this part on p-n junctions particularly useful.
