Example gold, water, etc. Where an insulator is a substance that blocks the flow of current through a medium. Example wood, glass, etc and a semiconductor is a substance that partially allows the current to flow and partially blocks the current flow. Silicon, germanium, gallium arsenide are a few examples of semiconductor materials.

What is N-type Semiconductor : Doping & Its Energy Diagram. The semiconductor materials include four electrons in their valence shell (external shell) like Ge (germanium) and Si (silicon).

The animations in the original were huge for the time (hydrogen was about 12 megabytes), so downloading and saving them was a wise use of bandwidth—or one could buy a CD for $37 (20 pounds). Now the videos stream and the CD seems no longer on offer. We wish we had saved one of the first edition videos, for the sake of comparison.
