I How does negative power link to amplification?

  1. Apr 30, 2016 #1
    So I've been studying electrons behavior in a semiconductor superlattice and I am currently analyzing the negative slope for the drift velocity against electric field. This is where negative differential velocity (NDV) takes place. I understand how NDV leads to negative power, but I can't quite grasp how that would relate to amplification?

    Any help or points in the right direction would be great!
