THIS SITE has some very good interactives for charged particle motion in fields,
Thomson's e/m experiment, photoelectric effect, quantum physics and the Millikan oil drop experiment.
Crookes tube simulation nice and simple
Excellent! Choose Einstein's Legacy: TV Screens, Laptop Screens or Applet thumbnails for all sorts of good stuff here!
The 20th Century part of this site gives info on Cathode rays
A simple-to-use animation which demonstrates the photoelectric effect
A NICE, SIMPLE SOLAR CELL EXPLANATION CAN BE FOUND HERE
(Choose 'See the flash movie on photovoltaic cells')
Some good animations of electron hole flow
For band structures of conductors, semiconductors and insulators, this animated tutorial is quite good.
How superconductors work
Useful information on resistance and superconductivity
(mainly the first animation on conductivity and a bit at the end about superconductors)
Most useful information on SUPERCONDUCTORS
Superconductors are beautiful!
