प्रश्न

Why is zener diode fabricated by heavily doping both p- and n-sides of the junction?

उत्तर

A zener diode is fabricated by heavily doping both p- and n-sides of the junction so that its depletion region formed is very thin and the electric field of the junction is extremely high, even for a small reverse bias voltage.
