Answer:
6.5 × 10¹⁵/ cm³
Explanation:
Thinking process:
The relation [tex]N_{o} = N_{i} * \frac{E_{f}-E_{i} }{KT}[/tex]
With the expression Ef - Ei = 0.36 × 1.6 × 10⁻¹⁹
and ni = 1.5 × 10¹⁰
Temperature, T = 300 K
K = 1.38 × 10⁻²³
This generates N₀ = 1.654 × 10¹⁶ per cube
Now, there are 10¹⁶ per cubic centimeter
Hence, [tex]N_{d} = 1.65*10^{16} - 10^{16} \\ = 6.5 * 10^{15} per cm cube[/tex]
