Answer:
6.5 × 10¹⁵/ cm³
Explanation:
Thinking process:
The relation ![N_{o} = N_{i} * \frac{E_{f}-E_{i} }{KT}](https://tex.z-dn.net/?f=N_%7Bo%7D%20%3D%20N_%7Bi%7D%20%2A%20%5Cfrac%7BE_%7Bf%7D-E_%7Bi%7D%20%20%7D%7BKT%7D)
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, ![N_{d} = 1.65*10^{16} - 10^{16} \\ = 6.5 * 10^{15} per cm cube](https://tex.z-dn.net/?f=N_%7Bd%7D%20%20%3D%201.65%2A10%5E%7B16%7D%20%20-%2010%5E%7B16%7D%20%5C%5C%20%20%20%20%20%20%20%20%20%20%20%3D%206.5%20%2A%2010%5E%7B15%7D%20per%20cm%20cube)
