Which element can be used as a dopant in a p-type semiconductor?

gallium

arsenic

antimony

phosphorus

gallium

Explanation:

Gallium is the element that would be best suited as a dopant for p-type semi-conductor because it belongs to the third group on the periodic table.

Elements with 3 valence electrons are best used as dopant for p-type semi-conductors.

A dopant is a material used to produce a broad range of characteristics in semi-conductors. Semi-conductors allows heat and electricity to pass through under some certain conditions. In n-type semi-conductors elements with 5 valence electrons are best used. Gallium is the only element in this choice that have 3 valence electrons and this will favor its usage as a dopant in a p-type semi-conductor.
