This Plasma frequency in option 6 is for metals and intraband transitions (Drude model).
What you mean is the plasma frequency in semiconductors. Plot the eloss function and you will see your peak. This Plasma frequency is related to a zero in epsilon1. (See a recent PRB about VEELS on my homepage (2013). Am 23.07.2013 05:31, schrieb Yasir Ali:
Hi Thanks Peter Blaha for reply. I have semi conductor and EELOSS have peaks in its graph.
