Function for calculate the exciton distribution. We usually use this equation for organic material. Behavior of exciton will follow this equation. You can see the detail in Subroutine_exciton1D.

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

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
5
2e-14 20000 3000 1e-12 1
2e-14 20000 3000 1e-12 1
