Q: What is the band gap energy of silicon at room temperature?
Solution:
The band gap energy of silicon at room temperature is approximately 1.1 eV.
Steps: 5
Show Steps
Step 1: Understand what band gap energy means. It is the energy difference between the valence band and the conduction band in a material.
Step 2: Know that silicon is a semiconductor material.
Step 3: Learn that at room temperature (about 25 degrees Celsius), silicon has a specific band gap energy.
Step 4: Find the value of the band gap energy for silicon, which is approximately 1.1 electron volts (eV).
Step 5: Conclude that the band gap energy of silicon at room temperature is 1.1 eV.
