Silicon Crystal Electron Flow
This interactive simulation was written to as a Flash artwork precursor for more advanced concepts.
-
Note that the (artwork precursor) is inaccurate in several ways:
- The Silicon N type Phosphorous doping normally isn't this dense.
- Electrons were made bigger here for visibility
- Atoms were spread further apart here for visibility
- Silicon (like Carbon) should have tetrahedral bonds

While I favor Flash, most of these are programmed as Java Applets.
- In general, Flash is expensive, but has better artwork (via integration with other Adobe products) and produces smaller run time files. Java, on the other hand, is free.
