Thermocouples, seeback effect, fermi energies

  1. Mar 9, 2005 #1
    Hello there fellow physicist,

    Well for my A2 investigation I have done Thermocouples. I investigated the potential difference produced by different metal combinations. Now I need a hypothesis of some sort. What property of a metal will influence the potential difference produced by a thermocouple? I have done a bit of research on the net and have found that the whole thermocouple equation has the fermi energy level terms in it. Now I have found fermi energies for some of my metals but couldnt find it for titanium, or the alloys (constantan and bronze). Any help will be much appreciated.

    So does anyone know what influence the potential difference produced?
    Or the fermi energy of titanium? at 0K
