Compute the structure factor for both the disordered and ordered states and determine which reflections are only present in the ordered state; these are known as superlattice reflections.
What is Superlattice Reflections?
A superlattice (SL) is a structure in which two different materials are grown in alternating layers to a specified thickness. home:
Nitride semiconductor light emitting diode (LED)
Therefore, Compute the structure factor for both the disordered and ordered states and determine which reflections are only present in the ordered state; these are known as superlattice reflections. Order and superlattice reflections: in the disordered state,Cu3aAuhas an fcc structure, with lattice parametera=0.3749Â nm. In the ordered state, Au occupies the corners of the cell, whereas the Cu atoms occupy the Gace centers. (Assume that the lattice parameter remains constant).

How about the Boston Tea Party? I don't know much about it but I heard it's a good event to write about :)
