    摘要： The present disclosure relates to an SEM-EDS analysis holder device configured to fix a sample in an SEM-EDX analysis apparatus. More specifically, the present disclosure relates to an SEM-EDS analysis holder device capable of minimizing damage to a sample and reusing the sample. An object of the present disclosure is to provide an SEM-EDS analysis holder device capable of minimizing damage to a sample and reusing the sample in an SEM-EDX analysis apparatus configured by attaching an energy dispersive X-rays spectroscope (EDS) detector to scanning electron microscopy (SEM). Another object of the present disclosure is to provide an SEM-EDS analysis holder device that is easily attached or detached and includes chemical components detected by an EDS detector without a component of a holder.

    摘要： 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.
