When an element of fifth group is doped in pure germanium/silicon due to excess of an electron, the semiconductor is known as n-type semiconductor. In n-type semiconductor, majority of carrier is electron. If the element of third group is added, the semiconductor is known as p-type. In this case, majority of carriers is hole.
The correct answer is: boron and aluminium
The correct answer is: boron and aluminium

Both Boron and Aluminium are trivalent. that is they have 3 electrons in outermost shell. so when the Si crystal is doped with them, one neighbouring Si atom can not form a bond and this incomplete bond results in a hole. so B and Al are P type dopants.
