Semiconductor Devices: pn Junction
... No current flows. Why? For significant current, we need to get more holes from n-side to p-side. Somehow we need to counteract the built-in potential that resists e– diffusion to p-side (and vice-versa for holes). But here we have increased the potential barrier for e– transfer! 3. Forward bias: cur ...
