MCQ
A silicon speciman is made into a $P-$type semi-conductor by dopping, on an average, one Indium atom per $5 \times 10^7$ silicon atoms. If the number density of atoms in the silicon specimen is $5 \times 10^{28}$ atoms $/ \mathrm{m}^3$ then the number of acceptor atoms in silicon per cubic centimetre will be
- A$2.5 \times 10^{30}$ atoms $/ \mathrm{cm}^3$
- B$1.0 \times 10^{13}$ atoms $/ \mathrm{cm}^3$
- ✓$1.0^{\times 10^{15}}$ atom $/ \mathrm{cm}^3$
- D$2.5 \times 10^{36}$ atoms $/ \mathrm{cm}^3$
