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.
