$activateStimEL is a command used to enable the calculation of stimulate Emission.
The stimulate emission coefficient is calculated by:
is the radiative recombination coefficient
is the threshold recombination rate
is the spontaneous radiative recombination rates decided by
is the fitting coefficient.
The way to activate the command is as following
$activateStimEL Method QW_number 1st_QW_layerNum 2nd_QW_layerNum 3rd_QW_layerNum ...
..... ..... total N layers (regions)
Method: 1 -> Givenand
of each layer. If this is layer is not QW, set
Method: 2 -> defined for future expansion
,
: Not used. It might be used when Method 2 is activate in the future
For example:
$activateStimEL 1 1 2 0.000 5.0e27 0.00 0.00 1.000e-4 5.0e27 0.00 0.00 0.000 5.0e27 0.00 0.00 0.000 5.0e27 0.00 0.00
In this command, use method 1. There is 1 QW which is the 2nd layer. The and of the 2nd layer is 1.0e-4 and 5.0e27 
The $activateStimEL setting for 1D-DDCC in GUI interface
Select the method in step 3.
The number assigned to each method:
Select QW_number.
The $activateStimEL setting for 2D-DDCC in GUI interface
1. After setting up the general structure, press Additional Function.
2. Check the box for Stimulate emission setting and fill in these fields as needed!
