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

Overview[edit]

The general form of the equation is

Equation upper D equals mu k Subscript upper B Baseline upper T

Where

For diffusion of carriers the special form is more appropriate.

Equation upper D equals StartFraction mu k Subscript upper B Baseline upper T Over q EndFraction

Where Equation q is the elementary charge.

Then for semiconductors

Equation StartFraction upper D Subscript n Baseline Over mu Subscript n Baseline EndFraction equals StartFraction k Subscript upper B Baseline upper T Over q EndFraction equals StartFraction upper D Subscript p Baseline Over mu Subscript p Baseline EndFraction
