What is Einstein's Equation for electrons?

The Einstein's equation for electron depicts that the electron diffusion constant is equal to the electron mobility of a particle with a particular thermal energy. Einstein noted that the diffusion coefficient D of a Brownian particle moving in a fluid is related to its mobility U via the relation D=kTU, where k is the Boltzmann constant and T is the temperature of the fluid.

How to Calculate Electrons Diffusion Constant?

Electrons Diffusion Constant calculator uses Electron Diffusion Constant = Mobility of Electron*(([BoltZ]*Temperature)/[Charge-e]) to calculate the Electron Diffusion Constant, Electrons Diffusion Constant formula is based on Einstein's Equation which essentially states that the diffusion constant of electrons is directly proportional to the product of the mobility of electrons and the thermal voltage (kT/q). In simpler terms, it links how quickly particles diffuse through a medium with their ability to move in response to an electric field and the thermal energy present in the system. Electron Diffusion Constant is denoted by Dn symbol.
