Any concerns can be shared but not accounted for. p-type semiconductors Obtained when a group 14 element is doped with group 13 element. Holes responsible for conduction. Example: aluminum doped in silicon. n-type semiconductors Obtained when group 14 elements doped with group 15 elements. Electron is responsible for electrical conduction. Example: Arsenic doped in silicon.
