Derive einstein’s relation in semiconductors
WebDiffusion current is a current in a semiconductor caused by the diffusion of charge carriers ( electrons and/or electron holes ). This is the current which is due to the transport of charges occurring because of non-uniform concentration of charged particles in a semiconductor. http://web.mit.edu/6.012/www/SP07-L3.pdf

WebRemarkably, we find that Einstein’s relation is still satisfied, even with these corrections. The new diffusion-drift equations, together with Poisson’s equation for the electric field, form the high-field semiconductor equations , which can be expected to be accurate regardless of the strength of the electric fields within the semiconductor. http://uigelz.eecs.umich.edu/classes/pub/eecs517/handouts/einsteins_relation.pdf
