Diffusion Coefficient of Electron Solution

STEP 0: Pre-Calculation Summary

Formula Used

Electron Diffusion Coefficient = Mobility of Electron*[BoltZ]*Absolute Temperature/[Charge-e]
D_E = μ_e*[BoltZ]*T/[Charge-e]
This formula uses 2 Constants, 3 Variables

Constants Used

[Charge-e] - Charge of electron Value Taken As 1.60217662E-19
[BoltZ] - Boltzmann constant Value Taken As 1.38064852E-23

Variables Used

Electron Diffusion Coefficient - (Measured in Square Meter Per Second) - Electron Diffusion Coefficient is a measure of the ease of electron motion through the crystal lattice. It is related to the mobility of the carrier, electron in this case.
Mobility of Electron - (Measured in Square Meter per Volt per Second) - Mobility of Electron is defined as the drift velocity of the electron per unit electric field.
Absolute Temperature - (Measured in Kelvin) - Absolute Temperature represents the temperature of the system.

STEP 1: Convert Input(s) to Base Unit
