There’s a variety of computational techniques that help us establish some confidence on the materials. Atomistic simulations can estimate stability and bulk properties of a new material, and we have synthesis experts (min qualification: PhD in thin film deposition) come up with rubrics on how to judge if a material/synthesis recipe is worth trying. All these approaches have known limitations, and improving them is the bulk of our work as a company! There’s also a lot of work to be done in figuring out the minimal set of experiments required to know if a research direction/material set is worth pursuing
