This is a funny idea from a group of students of physics, a guide to semiconductors with Britney Spears... Well, that's true, skimming through the tutorial pages it is possible to look at pictures of the worldwide known "singer".

I do think this is a great idea, since "semiconductor physics" could be a real drag for more than a few students.
Even though it sounds a bit odd to associate Britney to junctions and doping (oooops not the right coupling). I dare say this guide to semiconductor physics is a well done job!
