MHT CET Physics question

Not in JEE Advanced syllabus

In a general purpose diode avalanche breakdown is more common than Zener Breakdown because

(A)It is heavily doped
(B)Here covalent bands are weak
(C)It is lightly dopedCorrect
(D)It is not doped

Answer: (C)

Solution

A general purpose diode is lightly doped, so its depletion layer is wide and the field is too weak to pull electrons out of bonds (Zener effect) before carriers gain enough energy for
