How Semiconductors and Transistors Work

John C. Bean - WeCanFigureThisOut.org

Show • 21 episodes

This podcast is drawn from the "Virtual Lab" of WeCanFigureThisOut.org. This Virtual Lab uses 3D virtual reality animations to explain electronics, microelectronics and nanotechnology. This podcast explains how semiconductors work and how they are made into the transistor switches that power modern integrated cirtuits.

Here is our do it yourself silicon atom kitEpisode • Jul 24, 2017

First, let's make the nucleus of the atomEpisode • Jul 24, 2017

Add the first two electronsEpisode • Jul 24, 2017

And six moreEpisode • Jul 24, 2017

And finally the four bonding electronsEpisode • Jul 24, 2017

Move them farther apartEpisode • Jul 24, 2017

Make a 2nd atom and form a bondEpisode • Jul 24, 2017

Start to make a crystalEpisode • Jul 24, 2017

Take a look at its planes and facetsEpisode • Jul 24, 2017

Make a bar of silicon crystalEpisode • Jul 24, 2017

Create a donor atom with 5 bonding electronsEpisode • Jul 24, 2017

Put it into the silicon crystalEpisode • Jul 24, 2017

The donor's electron starts to wanderEpisode • Jul 24, 2017

More donors => a cloud of electronsEpisode • Jul 24, 2017

Put donor atoms into the other end of the barEpisode • Jul 24, 2017

Does the bar conduct? Not yet!Episode • Jul 24, 2017

But add metal plate just above the bar . . .Episode • Jul 24, 2017

The positive plate draws in the electronsEpisode • Jul 24, 2017

Completing this MOS transistorEpisode • Jul 24, 2017
