 $R_{\rm sp}(x)$ depends on position $x$ because the densities depend on position. $R_{\rm sp}(x)$ depends on position $x$ because the densities depend on position.
 The bimolecular recombination coefficient $c_{\rm rad}$ is a material dependent constant and has units ${\rm cm}^3/{\rm s}$. The bimolecular recombination coefficient $c_{\rm rad}$ is a material dependent constant and has units ${\rm cm}^3/{\rm s}$.
 +The order of magnitude is around $10^{-10}{\rm cm}^3/{\rm s}$.
  
 This recombination rate is coupled into the drift-diffusion equation and the stationary solution of the problem, This recombination rate is coupled into the drift-diffusion equation and the stationary solution of the problem,
