Animation of carrier flow in a metal. This movie loops indefinitely showing electrons moving about on both sides of the substrate Positive and negative poles are shown with electrons moving in opposite directions.

This online video is an animation of carrier flow in a semiconductor. Electrons move about on both sides of the substrate, and positive and negative poles are shown. The semiconductor is sandwiched in-between opposing...

This animation shows band populations as a function of temperature in an n-type semiconductor. Note that the Fermi-energy actual shifts position in the band gap and is not accurately depicted here. The video shows the...

This animation shows band populations as a function of temperature in a p-type extrinsic semiconductor. Note that the Fermi-energy actual shifts position in the band gap and is not accurately depicted here. The video...
