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