Perfect periodic ion lattice has no electrical resistance.As we know,this can be easily shown by solving the Schrodinger equation using Bloch therom.Yet,another explanation is that "in a periodic array of scatterers a wave can propagate without attenuation because of the coherent constructive interference of the scattered waves."(Ashcroft,Solid state physics)(adsbygoogle = window.adsbygoogle || []).push({});

Does anyone know where to find the quantitative verification of this explanation,for example,in 1D periodic sqare well potential?
