Stokes-Einstein Relation is a relation between the diffusion coefficient of charge carriers and carrier mobility.

Overview

The general form of the equation is

Where

• is the diffusion constant
• is the carrier mobility
• is Boltzmann's constant
• is the temperature

For diffusion of carriers the special form is more appropriate.

Where is the elementary charge.

Then for semiconductors
