Abstract: An electronic device for obtaining common supercell information according to an embodiment of the inventive concept stores first and second lattice matrices, indicative of surface structures of two different materials in a real plane, and a conversion table. The processor retrieves these matrices, obtains complex lattice matrices for both surfaces in a complex plane, and determines a lattice constant ratio from them. Using this ratio, the processor refers to the conversion table to obtain phase information and a conversion matrix. Finally, it calculates common supercell information for both materials based on the lattice constant ratio, phase information, and conversion matrix, and outputs it via the user interface device.
