Function for calculate the exciton distribution. We usually use this equation for organic material. Behavior of exciton will follow this equation.


\frac{dn_{ex}}{dt}=D{\nabla}^2{n_{ex}(r)}-\frac{n_{ex}(r)}{\tau}-\gamma{n_{ex}(r)}^2+G


Where 

  • D is diffusion coefficient.
  • \tau is relaxation time of exciton.
  • \gamma is annihilation rate constant.
  • G is exciton generation rate.

Format

$callexciton
n
d kr knr gamma g

Parameter Explanation

  • n : the number of tables we usually set n as 5.
  • d : diffusion coefficient. (cm^{2})s^{-1}
  • kr : radiatvie rate constant (s^{-1})
  • knr :non-radiative rate constant (s^{-1})
  • gamma : quenching coefficient. (cm^{2})s^{-1}
  • g : generation rate if you wanna let whole recombination rate change into exciton you should set g as 1.

Example

$callexciton
