Q Suppose a pure Si crystal has 5 × 1028 atoms
m–3 It is doped by 1 ppm concentration of
pentavalent As Calculate the number of electrons and hole (Given
that ni = 1 5 × 1016
m–3 )

Dear
student,
Here numbers of electron( n e)
=5×1028106=5×1022 m -3
We know
ni2 =nh×ne⇒nh=ni2ne=1 5×1
5×10325×1022=4 5×109m-3
Regards
