Question
Semiconductor material doped with Pentavalent impurity has majority carriers of
- (1 Point)
- holes
- electrons
- neutrons
- protons
Solution
Semiconductor material doped with Pentavalent impurity has majority carriers of electrons.
Here's the step by step explanation:
-
Semiconductors are materials that have properties between conductors and insulators. They are not very good at conducting electricity, but under certain conditions, they can do so.
-
Doping is the process of adding impurities to semiconductors to change their properties. In this case, the semiconductor is doped with a Pentavalent impurity.
-
Pentavalent impurities have five valence electrons. When added to a semiconductor, four of these electrons form covalent bonds with the semiconductor atoms, and the fifth electron is free to move around.
-
This free electron increases the conductivity of the semiconductor. Therefore, in a semiconductor doped with a Pentavalent impurity, the majority carriers of charge are electrons.
