Potential barrier, Physics

Assignment Help:

The potential difference created across the P-N junction due to the diffusion of electron and holes is called potential barrier.

For 2252_22.pngand for silicon 

 

On the average the potential barrier in P-N junction is ~ 0.5 V and the width of depletion region ~ 10-6.

So the barrier electric field.
