In a doped semiconductor, what is the absence (deficiency) of an electron called?
Answer & explanation
Correct answer: option 4
Th correct answer is Option 4: none of these.
In a doped semiconductor, the deficiency of an electron is called a hole.
Option 1: Proton — This is a subatomic particle found in the nucleus of an atom. While it has a positive charge, it is not a charge carrier in a semiconductor.
Option 2: Positron — This is the antimatter counterpart of an electron. It is not found in standard semiconductor physics.
Option 3: Neutron — This is a neutral subatomic particle in the nucleus and plays no role in electrical conduction.
