Parameter Explanation
- Dope : The doping concentration of the material.
- Ea : The activation energy of the material.
- Eg : The bandgap of the material.
- dix : The relative dielectric constant in x-direction.
- diy : The relative dielectric constant in y-direction.
- Eoff : The conduction iband offset of this layer and next layer.
- m0off : The parallel effective mass of electron.
- m0in : The perpendicular effective mass of electron.
- mhh : The heavy hole effective mass.
- mlh : The light hole effective mass.
- impurity : The background doping concentration.
- mun : Electron mobility.
- mup : Hole mobility.
- taun : Electron carrier lifetime.
- taup : Hole lifetime.

The $parameters setting in GUI interface is here
1. In this case, I chose Silicon as my material.
2. Press Material Parameter and set the Composition(x) = 1, then the material become Silicon.
3. Press Re-plot the depiction of material structure to refresh the figure!
4. I checked the 15 boxes for the parameters we need to make them clearer.
5. Now, fill in the table for Material Parameters, similar to the blue box!
