(A Five Minute Tutorial)

- Main Concepts To Learn:
- Fermi level, Ef, and the occupation probability of quantum states by an electron
- Temperature effect on electron distribution.
- A Quick Step-By-Step For Each Topic:
- Topic-1:
__Fermi level, Ef, and the occupation probability of quantum states by an electron__ - Using mouse, click and hold down the Ef -------------- line, and move up-and-down.
- Observe the electrons (
**.**) occupying or vacating quantum states (**__**) - Try to relate this phenomenon to the value of Fermi Function,
**f(E)**. The f(E) value is the probability of occupation. - Topic-2:
__Temperature effect on electron distribution__ - Use the scroll bar at the bottom of applet to change the Temperature.
You may click and hold the
**arrow**or drag the bar**|**. - Observe both the change of shape in f(E), left figure, and the corresponding electron distribution, right figure.
- Does high T give you a more gradual occupation in states around Ef level ? How about T=0K ? [applet shows some bug at T=0K.]
