Semi-conductors (1 Viewer)

[allGenreGamer]

I need to clarify some points about semi-conductors. Please tell me if the below are correct:

- Outer shell is full of electrons at absolute-zero.
- As temperature increases, some electrons will leave the bond and enter the conduction band.
- Intrinsic conduction will now occur.
- If an electric field is applied, the electrons move in opposition directions to the hole.

Thanks in advance.

yeah it all seems right.
the valence band is full of electrons at absolute zero, and that the conduction band is empty.

Where on the net, can I get info on superconductors?

does anyone know the correct doping ratio for n type and p type semi-conductors is it 1:10000000 or 1:100000 or 1:10000???
