Show affiliationsIt is demonstrated that the origin of the low-Q features in the static structure factor of disordered solids, such as the first sharp diffraction peak, can be understood by studying structural characteristics of their crystalline counterparts. The positionally disordered lattice models exhibit the first sharp diffraction peak at approximately the same position as in corresponding disordered structures. The availability of the exact solution for lattice models gives an opportunity to identify the reciprocal space vectors which contribute most to this peak.
