Virtual Lab: Semiconductor Crystals

© 2003-Present, John C. Bean
This presentation explains the atomic structures of "elemental semiconductors" (such as carbon & silicon) and those of "compound semiconductors" (such as GaAs, AlAs, GaP, CdTe . . .)

The presentation employs interactive 3D models that you can alter via selection buttons and then rotate, move or magnify.

These models are now displayed using secure "Three.js" JavaScript (replacing earlier use of the "Flash" plugin). But these models, especially the more complex ones, take a while to load into your browser. And the buttons take even longer to become active. These delays are particularly long the first time you view this presentation (taking 10’s of seconds). PLEASE BE PATIENT.
