### Electrical Mobility Calculator:

Enter the Electrical mobility mm²/(V·s), Temperature in °C, Charge in e ,and you get the calculation of Diffusion constant in mm²/s.

Einstein relation formula is the diffusion constant D_{(mm2/s)} in millimeter^{2} per second is equal to the electrical mobility μ_{(mm2)} in millimeter^{2} and multiply the Boltzmann constant K B_{(j/k)} in joules per kelvin and multiply the temperature T_{(0c)} in degree Celsius and divided by the charge of the carriers q_{(e)} in electron.Hence the Einstein relation formula can be written as

D_{(mm2/s)}= μ_{(mm2)} * K B_{(j/k)} * T_{(0c)} / q_{(e)}

Where

D= diffusion constant

μ = electrical mobility

KB = Boltzmann constant and KB=1.3806503 *10^{-23} J / K

T= temperature

Q = charge of the carriers
