	Introduction
	Welcome to this basic tour of semiconductor physics! Two of our most excellent guides, Sally Con and Jerry Manium, will take you through. Sally and Jerry explain things in different ways. Sally tries to be correct, and likes to stick to the facts. Jerry is easy-going, and uses examples from the everyday world around us. But, before you start the tour, you may want to test your knowledge with our semiconductor quiz. If you don't do as well as you'd have liked to, come back and let Sally and Jerry explain a few things!
