Question

Classify semiconductor into n or p types b doped with si

Answer 1

When B(Boron) doped with Si(Silicon) ,
silicon have 4 velence electron and boron
have 3 velence electron then these two
elements doped together then boron's 3
electron make only three covelent bond with
silicone electrons in the last orbit then one
electron Shortens to make bond with one
remaining electron of silicon this Shortens will
react as hole this hole react as positive charge so it is 'p' type semiconductor

so it is " P " type semiconductor

Answer 2

Classify each of the following as being either a p-type or a n-type semiconductor:

${\bf{\pink{Si \:doped\: with\: B.}}}$

‘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.
