Solution

Semiconductor material doped with Pentavalent impurity has majority carriers of electrons.

Here's the step by step explanation:

  1. 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.

  2. Doping is the process of adding impurities to semiconductors to change their properties. In this case, the semiconductor is doped with a Pentavalent impurity.

  3. 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.

  4. 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.
