$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 -> Given and 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 1.000d-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
