$2Dexcitonpar

$2Dexcitonpar is the command to solve the exciton diffusion equations. Actually, the exciton solver is an external function that is currently under development. Therefore, there is no clear definition of excitation parameters.
The related commands are $2Dexcitonmode $call2Dexciton

The user can define their own 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( ).
