Which of the following is not correct about a step-graded junction in electronic devices?

Electronics and Communication Engineering (ECE) : Electronic Devices and Circuits - Quiz(MCQ)

They are designed with abrupt junction

Diodes with step-graded junctions are slower than a normal diode

Depletion layer penetrates more into the lightly doped region

None of the above

Correct Answer : Option (C) : Diodes with step-graded junctions are slower than a normal diode

Explanation : Step-graded junctions are designed with abrupt junctions. They are either p⁺– n or p – n⁺ junction and diodes with step-graded junctions are faster than the normal diodes.
