I spent about 20 minutes working with the applet and reading the accompanying textual material. This is a learning item in progress, as several parts (applet tutorial, worksheet, quiz, SPICE simulation) are just stubs, and only one reference is given, and that is not on-line. It could be effectively used as a lecture/demo, but probably not as a tutorial or homework without substantial instructor-supplied material. The applet has the flexibility to show or hide various functions (density of states, Fermi distribution, density of occupied states), and because of this the instructor will need to spend a lot of time explaining what is being shown. The default mode for the left display is too dense, but the applet gives the option of showing or hiding each of the various functions. The textual information currently in the introduction and mathematical analysis is not sufficiently clear for most students to understand the display on their own. The change in the energy distribution of the carrier density with temperature is particularly informative, in part because of its simple display.
