Answer:
The percentage of silicon atoms per unit volume that are displaced in the single crystal lattice = 0.001 %
The percentage of silicon atoms per unit volume that are displaced in the single crystal lattice with boron atoms = 0.4 ×
%
Explanation:
No. of phosphorus atoms = 5 × 
The volume occupied by a single Si atom


2 ×


= 5 ×


Put the values in above equation we get

PCT =
%
These are the percentage of silicon atoms per unit volume that are displaced in the single crystal lattice.
(b).
No. of boron atoms = 2 × 
The volume occupied by a single Si atom


2 ×


= 5 ×


Put the values in above equation we get

PCT = 0.4 ×
%
These are the percentage of silicon atoms per unit volume that are displaced in the single crystal lattice.
