Enumerating all possible alloys
We recently developed a new algorithm for generating all possible structures in an alloy. To the right is the output for a "square" binary alloy. The results for three dimensional cases can be combined with "fast" Hamiltonians to predict intermetallic ground states and optimize band-gaps and effective masses in semiconductor alloys. The algorithm was developed in collaboration with Rodney Forcade in the Math Dept. Read More
