Answer:
Detailed solution is attached below in three simple steps the problem is solved.
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.
