Derive einstein’s relation in semiconductors

In physics (specifically, the kinetic theory of gases), the Einstein relation is a previously unexpected connection revealed independently by William Sutherland in 1904, Albert Einstein in 1905, and by Marian Smoluchowski in 1906 in their works on Brownian motion. The more general form of the equation is • D is the diffusion coefficient; WebJul 20, 2002 · This writeup is about semiconductor physics.If you have no idea what it means, you could read my writeup in that node. The nodes conductivity, Fick's Law, diffusion, and p-n junction will also help. While it will be difficult to follow my derivation without a background in semiconductor physics, I think the result itself can be …
