Physics Semiconductor Electronics Intrinsic and Extrinsic Semiconductor MCQ (Single Correct)

In a -type semiconductor, which of the following statement is true

Holes are majority carriers and trivalent atoms are dopants.

Electrons are majority carriers and trivalent atoms are dopants.

Electron are minority carriers and pantavalent atoms are dopants

Holes are minority carriers and pentavalent atoms are dopants.

Text Solution

Verified by Experts

The correct answer is:

In an -type semiconductor, we add pentavalent impurities (like ).

These provide extra electrons, so electrons are the majority carriers.

Holes become minority carriers.
