- TL;DR : Can't figure out what N(E) vs. E graph means in AES
Hi all, my name's Ethan and I'm an undergraduate physics student conducting research on work functions this summer. I've been trying to understand the graphs of N(E) or N'(E) vs. auger electron energy for several days now, but I can't find in the literature what exactly N(E) or N'(E) are. I've seen N(E) referred to as electron yield, intensity, and even dI/dV, but nowhere have I seen a clear definition. I understand why N'(E) is often used instead of N(E), since the peaks where Auger electrons are emitted are often difficult to see on the N(E) graph, I just don't understand what either actually are. I've attached a picture below that shows an N'(E) vs. E graph for some more context. Thanks!
