Optical spectrum question

[Heinz]

Hi,

I plotted the optical spectrum of silicon following the tutorial. How can I plot the Re(eps) and Im(eps) versus frequency not the energy?

Best regards

You need to save the data of the plot, by right clicking and then you can transform energy to frequency by dividing by plancks constant.
You can also do this in python with pylab by following the example in the tutorial.
