WebDebye=Waller factor does not produce incoherence nor decoherence. When this is applied to the scattering of an electron at the top of a fermi sea at zero temperature by either an electron gas in a metal or by impurities, each individual scattering is reduced by its individual Debye-Waller factor. But there is no inelastic scattering because WebThere are different Debye-Waller, temperature or thermal vibration terms in use. Finally you will find them all described in fundamental XRD books.
