Reverse Bias
Now we can consider the effects forward bias station. Figure 3.21a the reverse bias (metal and a negative voltage between the N-type semiconductors) shows the case of . N-type semiconductor with a negative voltage applied to the metal and the amount of which is the semiconductor Fermi level above the Fermi level indicates the presence of

This current is almost independent of the reverse voltage." I_s, the reverse bias saturation current for an ideal p-n diode is given by,
