In a p-type semiconductor, the current conduction is primarily due to the movement of positively charged carriers called "holes."
In p-type semiconductors, a small number of atoms are intentionally doped with elements that have one less valence electron than the atoms of the semiconductor material. This creates "holes" in the valence band, which can be thought of as positively charged mobile vacancies that can move through the crystal lattice when an electric field is applied.
When a voltage is applied across a p-type semiconductor, these holes move in the direction opposite to the electric field. This movement of holes constitutes the conduction of current in a p-type semiconductor. Essentially, the valence band acts as the dominant carrier of charge, and the movement of holes from one location to another contributes to the flow of electric current.
In summary, in a p-type semiconductor, the current conduction is primarily due to the movement of positively charged carriers known as "holes."
