Metal's plasmon frequency

  1. Dec 3, 2009 #1
    Hi guys;

    I have a question about the Plasmon frequencies in metals I know that it can be calculated as following:
    I was just wondering if anyone knows it is possible to change the plasmon frequency of any metal let say silver experimentally or not. I am working on metallic photonic crystals I want to find the effect of plasmon frequency on photonic band gap.

    Change either the electron density or the electrons effective mass.
