Questions & Step-by-Step Solutions
What is the bandgap energy of silicon at room temperature?
Step 1: Understand what bandgap 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, which means it can conduct electricity under certain conditions.
Step 3: Learn that the bandgap energy of silicon is important because it determines how easily electrons can move from the valence band to the conduction band.
Step 4: Find out that at room temperature (about 25 degrees Celsius), the bandgap energy of silicon is approximately 1.1 electron volts (eV).
Step 5: Recognize that this value (1.1 eV) is crucial for the functioning of electronic devices made from silicon.
