Electrons in metal

  1. Jul 11, 2014 #1
    I just wanted to clear one thing... in metals what type of potential the electrons are subjected to..??
    Is it constant , sinusoidal , square or non-periodic..?? plzz explain a bit in accordance with free electron theory.>!!!

    It's complicated. The nuclei produce their 1/r type fields, and since they a periodic in a metal, the net field is periodic. Now not all the the electrons necessarily see this periodic 1/r type potential, b/c part of the potential is being screened by electrons. You can get qualitative results by using a sinusoidal potential, but quantitative results require more accurate potentials.
