When the p and n regions are used for high resistivity, the depletion region at the respective places is called _________

(a) Q and ϒ regions

(b) ϒ and π regions

(c) Q and π regions

(d) π and ϒ regions

The question was posed to me by my school principal while I was bunking the class.

My question is based upon p-i-n Diode and its Characteristics topic in section Semiconductor-Diode Characteristics of Electronic Devices & Circuits

The correct option is (d) π and ϒ regions

Easy explanation: When p region is used for high resistance, the depletion layer is high at p side.When n side is used the depletion layer is high at n side. They are called as π and ϒ regions respectively.
