WebJun 1, 1973 · The Einstein relation relates the diffusion coefficient to the mobility and is frequently used in semiconductor device analysis and design. A flux equation governing the behavior of mobile particles in semiconductor material is derived from the Boltzmann transport equation. The particles are assumed to obey quantum statistics. WebStokes-Einstein relation in the framework of SCGLE theory; however, DT ~ τ is not a good one but takinga fractional from as . DT ~ (τ) ξ. with an exponent ξ≠1 even the Stokes-Einstein relation is established in SCGLE theory. Keywords: Stokes-Einstein relation SCGLE theory Structural relaxation Diffusion Decoupling of

WebThe Einstein's relation shows that the diffusion coefficient, D, is directly proportional to the mobility, μ[(m2mol) (J s)−1]:31 D= μRgasT, (1) where Rgasis the universal gas constant … WebWhich is the famous Stokes-Einstein’s relation between the viscosity and diffusion coefficient. The Stokes-Einstein relation inspired the pioneering work of Perrin who studied the random walk of a colloidal particle using an ultramicroscope and found that the mean square distance (< 2>) covered in ‘t’ time is correlated with the diffusion ...
