Question

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
