Adds an (optical) generation region to the simulation environment where the generation profile has been imported into Finite Element IDE. This command requires a CHARGE solver region to be present in the objects tree.

Description |
|---|---|
|
addimportgen; |
Add an import generation object to the simulation environment. This function does not return any data. |
Once the import generation object is created, the optical generation data can be imported from a matlab (.mat) file using the GUI or by assigning a dataset to the object using the importdataset script command. The .mat file must contain a 3D matrix G containing the generation data on a rectilinear grid and the three coordinate vectors x, y, z. The dataset can be either a rectilinear or an unstructured dataset.
Example
The following script command will add an import generation object to the CHARGE solver region and will load an analytic 3D optical generation data into it.
addimportgen;
set("name","gen_opt");
set("x",0);
set("y",0);
set("z",0);
# create coordinate vectors and 3D matrix for doping profile
x = linspace(0,1e-6,11);
y = linspace(-1e-6,1e-6,2);
z = linspace(0,2e-6,101);
G = matrix(11,2,101) + 1e27; # assume uniform generation rate of 1e21 /cm3 (1e27 /m3)
# create dataset
gen = rectilineardataset("gen",x,y,z);
gen.addparameter("a",1); # add a dummy parameter
gen.addattribute("G",G);
# load data into doping object
select("CHARGE::gen_opt");
importdataset(gen);
