Hi Sangmyeong,

Unfotrunately, we dont have the poli-Si material (n,k) data on our Material Database but you can add the data on a .txt form from literature by simply clicking add.

You can collect the data (by digitized) from this plot for poly-Si.

This is the website where you can find the n nad k for different materials. If you want to do the model to demonstrate the experiment it is better to get measure n and k with ellipsometry for your grown sample. It always differ form the literature data.
