$2Dexcitonpar

$2Dexcitonpar is the command to solve the exciton diffusion equations. Actually the exciton solver is an external function which is developing. Therefore, there is no clear definition of exiciton parameters. user can define his won definition of these parameters. The format is

$2Dexcitonpar
N_column
excitonpar(1,1) excitonpar(2,1) excitonpar(3,1) excitonpar(4,1) excitonpar(5,1) ... excitonpar(N_column,1)
excitonpar(1,2) excitonpar(2,2) excitonpar(3,2) excitonpar(4,2) excitonpar(5,2) ... excitonpar(N_column,2)
excitonpar(1,3) excitonpar(2,3) excitonpar(3,3) excitonpar(4,3) excitonpar(5,3) ... excitonpar(N_column,3)
excitonpar(1,4) excitonpar(2,4) excitonpar(3,4) excitonpar(4,4) excitonpar(5,4) ... excitonpar(N_column,4)
...
...
...
...
excitonpar(1,n) excitonpar(2,n) excitonpar(3,n) excitonpar(4,n) excitonpar(5,n) ... excitonpar(N_column,n)

At 10/01/2024: par 1-6 are defined as

excitonpar(1,n) ->  D_ex  -> diffusion coefficient
excitonpar(2,n) ->  Kr  -> exciton radiative recombination
excitonpar(3,n) ->  Knr  -> exciton non-radiative recombination
excitonpar(4,n) ->  $\gamma$  -> exciton exciton quench
excitonpar(5,n) ->  K_SE  -> exciton - electron quench 
excitonpar(6,n) ->  K_SH  -> exciton - hole quench 

For example:

$2Dexcitonpar
6
1.0e-7  1.0e7 3.0e7  1.0e-10  1.0e-5  2.0e-5
1.0e-7  1.0e7 3.0e7  1.0e-10  1.0e-5  2.0e-5
1.0e-7  1.0e7 3.0e7  1.0e-10  1.0e-5  2.0e-5
.... N region need to have N layers

The summary of each loss will be outputted to the sum.json file

The user will use these parameters in subroutine exciton2Dquench( ).

After setting up the general structure, press OLED Setting, check the box, and fill in the fields for Dr, Kr, Knr, and Gamma as needed!
