$2Dexcitonmode

$2Dexcitonmode is the command to decide the exciton diffusion mode. The commnad is as follow

 $2Dexcitonmode
 Mode_id  excitontype

For example:

 $2Dexcitonmode
 1 1 

Mode_id :  1. The traditional mode, only consider single exciton type  
Mode_id :  2.  multiexciton mode update to 3  (excitontype =1 to 3)  

Excitontype ID = 1 :   1 exciton type   (such as only considering Singlet, or triplet) 
Excitontype ID = 2 :   2 exciton types   (such as both considering Singlet, and triplet) 
Excitontype ID = 3 :   3 exciton types   (such as considering Singlet, triplet, and doublet or something else) 

If mode =2 , the way for $2Dexcitonpar command need to be changed.

 $2Dexcitonmode
 2 2  

 $2Dexcitonpar

 Dn    means exciton diffusion coefficient
 Kr    means exciton recombination 
 Knr   mean  exciton nonradiative recombination 
 EEA   means exciton exciton anealing 
 KEnQ  means exciton electron quench
 KEpQ  means exciton hole\ quench
 Ketr21 means exciton tranfer from 2 to 1  
 Ketr32 means exciton tranfer from 3 to 2   ....
 KEE12   means exciton exciton fussion transfer from 1 to 2 
 KEE23   means exciton exciton fussion transfer from 2 to 3
 RadG  (0-1.0)  means  Bnp ratio to generation of exciton 
 nonRadG  (0-1.0)  means  SRH recombination (trap asissted) to generation of exciton
