Why to subt ni from number of doped atom
Solution
Therefore, the number of electrons is approximately 4.99 × 1022 and the number of holes is about 4.51 × 109.
Hence the number of electrons is more than the number of holes, the material is an n-type semiconductor.
Therefore, the number of electrons is approximately 4.99 × 1022 and the number of holes is about 4.51 × 109.Hence the number of electrons is more than the number of holes, the material is an n-type semiconductor.
