$callexciton

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.

Singlet Rate Equation: 解析失敗 (語法錯誤): \frac{dn_{ex}^S}{dt}=D^S{\nabla}^2{n_{ex}^S(r)}-(k_{r}^S+k_{nr}^S+k_{e}^S \times n+k_{h}^S\times p){n_{ex}^S(r)-\gamma{n_{ex}(r)}^2+G Triplet Rate 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.

Parameter Explanation

• n : the number of tables we usually set n as 5.
• a : The type of exciton solver mode

 1: Time-dependent triplet solver 
 123: Time-dependent triplet and singlet solver (For TADF OLEDs model)
 3: Triplet Exciton Solver (For PhOLEDs model)
 6: Singlet and Triplet Exciton Solver (For TADF OLEDs model)
 4: Triplet Exciton Solver with exciton blocking boundary 

• b : Start time (For time-dependent solver)
• c : dt (For time-dependent solver)
• d : End time (For time-dependent solver)
• e : savenum (For time-dependent solver)
• 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.
