Abstract: A method for determining a stable structure of a multi-element crystal, the method including: determining a multi-layered matrix of the multi-element crystal based on a layer of the multi-element crystal and a composition ratio of transition metals included in the multi-element crystal; grouping candidate structures of the multi-element crystal into a plurality of candidate structure groups based on a trace of the multi-layered matrix; and determining at least one stable structure group including the stable structure from among the plurality of candidate structure groups to determine the stable structure.
