Q. 14.8 The number of silicon atoms per m3 is This is doped simultaneously with
atoms per
of Arsenic and
per
atoms of Indium. Calculate the number of electrons and holes. Given that
Is the material
or
?
Given:
number of Silicon atoms per =
number of Arsenic atoms per =
number of Indium atoms per =
number of thermally generated electrons
Now,
Number of electrons
=
number of holes is
in thermal equilibrium
Now, since the number of electrons is higher than number of holes, it is an n-type semiconductor.
