Parameter Explanation

  • Dope : The doping concentration of the material. (cm^{-3})
  • Ea : The activation energy of the material. (eV)
  • Eg : The bandgap of the material. (eV)
  • 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. (m_0)
  • m0in : The perpendicular effective mass of electron. (m_0)
  • mhh : The heavy hole effective mass. (m_0)
  • mlh : The light hole effective mass. (m_0)
  • impurity : The background doping concentration. (cm^{-3})
  • mun : Electron mobility. (cm^2s^{-1})
  • mup : Hole mobility. (cm^2s^{-1})
  • taun : Electron carrier lifetime. (Sec.)
  • taup : Hole lifetime. (Sec.)

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!
