Question
The impurity atoms with which pure silicon may be doped to make it a p-type semiconductor are those of [more than one option may he correct]
The impurity atoms with which pure silicon may be doped to make it a p-type semiconductor are those of [more than one option may he correct]
Open in App
Solution
The correct options are
B boron
D aluminium
As silicon lies in the group 14 of the modern periodic table thus to convert a pure silicon into a p-type semiconductor, it must be doped with impurity containing atoms which lie in group 13 in modern periodic table such as boron and aluminium.
