Hopg work function
Webequilibrated. Usually the analyzer work function is smaller than the sample work function, i.e. the contact potential results in an acceleration of the electrons as they fly through the analyzer. Consequently, the kinetic energy of all electrons increases by Φ s - Φ a, yielding E kin = hν-E b-Φ s +Φ s-Φ a= hν-E b-Φ a for the primary ...
