Question

$p-$type semiconductors are formed when $Si$ or $Ge$ are doped with:

• A. group 14 elements
• B. group 15 elements
• C. group 13 elements
• D. group 18 elements

Answer 1

The correct option is C group 13 elements

For $Si$ or $Ge$ to be a $p-type$ semiconductor, they have to be doped with trivalent elements. This will lead to electron scarcity, which is called as hole. For this reason, the elements should be of Group 13.

So, option $C$ is correct.
