How is barrier potential created

Web7 sep. 2024 · When there is an applied reverse bias voltage, a small potential barrier is formed for electron flow from metal to semiconductor. However, the small barrier will eventually vanish when the reverse bias voltage becomes larger. Consequently, there is a large reverse current flow when \(V < 0\). The \(I-V\) characteristic is shown in Figure 7(b).
