웹2024년 3월 20일 · The energy gap between the conduction band and valence bands determines the amount of energy required for an electron to break free. When an electron is free, it can take part in conduction. This energy gap is called the bandgap. It is often used to define the limits of conduction and optical devices. 웹1일 전 · The band gap is the minimum amount of energy required for an electron to break free of its bound state. When the band gap energy is met, the electron is excited into a free state, and can therefore participate in conduction. The band gap determines how much energy is needed from the sun for conduction, as well as how much energy is generated.
