Structure Factor Demo

This is an interactive demonstration of the Static structure factor. It allows you to plot both radially averaged and 2-dimensional structure factors for a variety of (2D) crystal structures, and to explore which particles contribute to specific peaks in the structure factor or diffraction pattern.

Features:

• Visualize the origin of different peaks in both the two-dimensional structure factor S(q) and its radial average S(q).
• Variety of possible crystal phases, including a hexagonal lattice, a square lattice, and a 12-fold quasicrystal.
• You can examine both perfect lattices and simulations that include thermal fluctuations.
