Question

What are some electrical properties of semiconductors?

✓

Answer

Electrical properties of semiconductors are different from metals and insulators due to their unique conduction mechanism.
The electronic configuration of the elemental semiconductors plays a very important role in their electrical properties.
They are from the fourth group of elements in the periodic table.
They have a valence of four.
Their atoms are bonded by covalent bonds. At absolute zero temperature, all the covalent bonds are completely satisfied in a single crystal of pure semiconductor like silicon or germanium.
