Semiconductors
|
Java via CheerpJ:
We've partnered with Leaning Technologies to allow our Java sims to run in a browser.
This sim is not compatible with iPads.
Java Version:
Supports offline use and offers improved performance.
Topics
- Semiconductors
- Diodes
- Transistors
Description
Dope the semiconductor to create a diode. Watch the electrons change position and energy.
Sample Learning Goals
- Recognize that the battery is the driving force in a circuit.
- Describe how n and p dopants change the structure of electron energy levels in a semiconductor.
- Explain why an np junction acts as a diode, allowing current to flow one way but not another.
