The number of silicon atoms per is This is doped simultaneously with atoms per of Arsenic and per atoms of Indium. Calculate the number of electrons and holes.

Number of silicon atoms is given as atoms

Number of arsenic atoms is given as atoms

Number of indium atoms is given as atoms

electrons

be the number of holes.

In the thermal equilibrium,

On Calculating, we get

As a result, the material is a n-type semiconductor as .
