A silicon specimen is made into a p-type semiconductor by doping, on an average, one Indium atom per 5×107 silicon atoms. If the number density of atoms in the silicon specimen is 5×1028 atoms/m3, then the number of acceptor atoms in silicon per cubic centimeter is :
- 2.5×1030 atoms/cm3
- 1.0×1013 atoms/cm3
- 1.0×1015 atoms/cm3
- 2.5×1036 atoms/cm3
Answer
(C) 1.0×10 15 atoms/cm 3
