A silicon specimen is made into a P-type semi-conductor by doping, on an average, one Indium atom per 
silicon atoms. If the number density of atoms in the silicon specimen is 
atoms/m 3 , then the number of acceptor atoms in silicon will be
A
atoms/cm 3
B
atoms/cm 3
C
atoms/cm 3
D
atoms/cm 3
Text Solution
Verified by ExpertsThe correct answer is:
C
Number density of atoms in silicon specimen
atoms- 
atoms 
.
Since, 1 atom of indium is doped in 
silicon atoms, so total number of indium atoms doped per 
of silicon will be
atom 
.
