The atoms are Pentavalent impurity atoms.
- These specific atoms are typically used to expand sufficiently the considerable proportion of conduction-band electrons
- These in common are five-valence electron atoms.
- For example, Arsenic, Phosphorus.
- Each of these specific atom typically forms covalent bonds that are adjacent to it.
- Four of these valence electrons are employed to shape covalent bonds with silicon atoms, with one secondary electron remaining.
