[QE-users] Optical properties

[Mehmet ERDEM]

Dear All,

I need to calculate Refractive/reflective index vs. Energy. I don't know what to use.

Using epsilon.x, I can find reel and imaginary parts. I know that there is a relationship between reflective/refractive index (n,k) and dielectric function (epsilon1-epsilon2), however I have converted epsilon to n  and plotted the graph (which didn't work).

So, how to calculate reflective/refractive index?

Thanks
