A silicon specimen is made into a p- type semiconductor by doping on an average one indium atom per 7
: 510
silicon atoms. if the number density of atoms in the silicon specimen is
28 3
510 atm/m then the no. of acceptor atoms in silicon per

cubic centimeter will be?

Dear Student,
Please find below the solution to the asked query:

No. of silicon atoms required for the case of 1 indium atom=5×107No. of silicon atoms in 1 m3=106 cm3 is 5×1028No. of silicon atoms in 1 cm3 is 5×1022Hence,No. of acceptor atoms=5×10225×107                                         =1×1015
