Derivation of built in potential

WebBand bending implies an electric field and, therefore, a potential difference across the junction. This “built-in” potential Vbi can be found as follows. If we look at the “raw” … WebThe significance of this built-in potential across the junction, is that it opposes both the flow of holes and electrons across the junction and is why it is called the potential barrier.
