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).

They wanted America to be a free country, so they encouraged people to come here for a fresh start. They wanted them to be able to be fre in what they chose to do.
People still follow this because there are people today who come here to do exactly that.
Answer:
- The sinking of the Lusitania
- The Zimmerman Telegram
Explanation:
German submarines attacked and sunk the Lusitania, a British passenger ship. This killed 128 Americans and created tensions between America and Germany.
Germany sent a telegram to Mexico to attack the United States. The United Kingdom was able to intercept the telegram and showed it the United States. The Zimmerman Telegram was the last straw for the United States.
