For 10 points, identify these structures whose constituent materials are found in repeating patterns, and whose three-dimensional arrangement is called a "lattice."
Anomalies in these structures may include ones which obey the conservation of charge that are named for Frenkel and Schottky. Their analysis invokes the reciprocal k-space, which is the Fourier transform of the real space describing them. In one technique used to analyze them, the incident angle that gives the maximum constructive interference is the inverse-sine of the wavelength multiple divided by twice the spacing in them according to Bragg's law. They are studied using X-ray diffraction.
