The formula to calculate the Electron Diffusion Constant (Dn) is:
\[ D_n = \mu_n \cdot \left( \frac{k \cdot T}{e} \right) \]
Electron Diffusion Constant refers to a material property that describes the rate at which electrons diffuse through the material in response to a concentration gradient. Mobility of electron is defined as the magnitude of average drift velocity per unit electric field. Temperature is the degree or intensity of heat present in a substance or object.
Let's assume the following values:
Using the formula:
\[ D_n = 180 \cdot \left( \frac{1.38064852E-23 \cdot 290}{1.60217662E-19} \right) \approx 4.49824643827345 \]
The Electron Diffusion Constant is approximately 4.49824643827345 m²/s.
