Abstract The concentration dependence of the electron diffusion length in p‐type GaAs is analyzed based on experimental values reported in the literature and recent studies of minority carriers mobility in GaAs. The dependence of L n with doping impurity concentration is determined for τ nr ≫ τ r and good agreement is found with highest reported experimental values of L n ; considerations are made about τ nr . The dependence of electron mobility, diffusion constant, and radiative recombination lifetime on concentration are also given.
