Important: You need a modern browser in order to savour the layout, especially the formulae, of this text. I show little mercy with those good old things called Netscape 4 or things like that, although with special tbook switches you could make your HTML files also work with older browsers; But already today the Internet Explorer 6 and Netscape 6 do an almost perfect job here. The generated HTML files are supposed to be valid strict HTML, but I wanted to keep some attributes like lang for compatibility. But tbook can also generate fancy XHTML 1.1 files.
BTW, it's a text about solid state physics, extremely thin wires, so-called quantum wires.]
