That relation gives a value of Boltzmann's constant times temperature over electric charge for the ratio of diffusivity and charge mobility, and is sometimes credited to this man and Smoluchowski.
A relation named for this man can be derived by expressing the gradient of the chemical potential in terms of the quasi-Fermi energy and plugging in Fick's first law. That relation gives a value of Boltzmann's constant times temperature over electric charge for the ratio of diffusivity and charge mobility, and is sometimes credited to this man and Smoluchowski. That relation appeared in his paper utilizing osmotic pressure to generate expressions for root mean square displacement of small particles suspended in a fluid. FTP, name this man who wrote a classic 1905 paper analyzing Brownian motion.
