A p-n junction is an interface or a boundary between two semiconductor material types, namely the p-type and the n-type, inside a semiconductor.
Unbiased P-N Junction
There are two operating regions in the P-N junction diode, P-type & N-type.
There are three biasing conditions for P-N junction diode and this is based on the voltage applied:
Forward Bias of the P-N Junction
Reverse Bias of the P-N Junction
P-N Junction Formula: The formula used in the p-n junction depends upon the built-in potential difference created by the electric field is given as:
where E0 is the zero bias junction voltage, VT is the thermal voltage of 26mV at room temperature, ND and NA are the impurity concentrations, ni is the intrinsic concentration
