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 Si as my material.




2. Press the Material Parameter and set the Composition(x) = 1, then the material become Si.
3. Press the Re-plot the depiction of material structure to refresh the figure!


4. To show it more clearly, I ticked off the 15 parameters we need.
5. Now, fill in the table for Material Parameters, similar to the blue box!
