Combinatorial sputtering creates compositional gradients from sputtering targets, yielding different crystals at different locations and potentially enabling hundreds or thousands of crystals to be tested in one run.

“So, you know, one thing people have tried is combinatorial sputtering, and if you've ever heard of this, like you have these sputtering targets and you create this compositional gradient, so when you look at the final product, because there is gradient from each precursor, it creates different crystals at different spatial locations. So in one go you may”

“You maybe try hundreds thousands of crystals”
