What is the energy band gap of a typical semiconductor? (2021)

Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions.
Step 2: Learn about the energy band gap. The energy band gap is the energy difference between the valence band (where electrons are) and the conduction band (where electrons can move freely).
Step 3: Know that different materials have different energy band gaps. For semiconductors, this gap is usually small compared to insulators.
Step 4: Find out the typical energy band gap for common semiconductors. For example, silicon is a common semiconductor.
Step 5: Look up the energy band gap value for silicon. It is approximately 1.1 electron volts (eV).
