Answer 2

‘PN junction diode’ can be defined as 2 terminal electronics element, where it can be categorized as linear graded or step graded.  

Explanation:

• The ‘PN junction diode’ can be considered as one the basic elements in the electronics field.

• In a linear graded type junction, the doping can be varied in a linear fashion along with the distance from the provided junction.  

• In a step ‘graded junction’, the concentrated dopants in the ‘N side and P side’ are uniformly up to the ‘junction’.
