Q. 20 B3.9( 20 Votes )
Classify each of the following as being either a p-type or a n-type semiconductor:
Si doped with B.
‘Si’ belongs to group 14th in the periodic table and ‘B’ belongs to group 13th. Thus, when ‘Si’ is doped with “B’, it makes hole or electron valance and acts as p – type conductor.
