Q: What is the energy band gap of silicon at room temperature?
Solution: The energy band gap of silicon at room temperature is approximately 1.1 eV.
Steps: 4
Step 1: Understand what an energy band gap is. It is the energy difference between the top of the valence band and the bottom of the conduction band in a material.
Step 2: Know that silicon is a semiconductor material commonly used in electronics.
Step 3: Recognize that the energy band gap can change with temperature, but at room temperature (about 25 degrees Celsius), it is a specific value.
Step 4: Find the commonly accepted value for the energy band gap of silicon at room temperature, which is approximately 1.1 electron volts (eV).
