Explain electron diffusion length.

Diffusion length is the average length a carrier moves between generation and recombination. Semiconductor materials that are heavily doped have greater recombination rates and consequently, have shorter diffusion lengths. Higher diffusion lengths are indicative of materials with longer lifetimes and are, therefore, an important quality to consider with semiconductor materials.

How to Calculate Electron diffusion length?

Electron diffusion length calculator uses Electron Diffusion Length=sqrt(Electron Diffusion Constant*Relaxation time) to calculate the Electron Diffusion Length, The Electron diffusion length is proportional to the square root of the mobility and carrier lifetime. Electron Diffusion Length and is denoted by Ln symbol.

Here is how the Electron diffusion length calculation can be explained with given input values -> 474.3416 = sqrt(22.5*1).

FAQ

What is Electron diffusion length?
The Electron diffusion length is proportional to the square root of the mobility and carrier lifetime and is represented as Ln=sqrt(Dn*𝛕) or Electron Diffusion Length=sqrt(Electron Diffusion Constant*Relaxation time). Electron Diffusion Constant is a factor determining the Diffusion length of electron and Relaxation time is the time in which the particle does not collide with any other particle.
How to calculate Electron diffusion length?
The Electron diffusion length is proportional to the square root of the mobility and carrier lifetime is calculated using Electron Diffusion Length=sqrt(Electron Diffusion Constant*Relaxation time). To calculate Electron diffusion length, you need Electron Diffusion Constant (Dn) and Relaxation time (𝛕).
