Abstract

Carbon impurities in MgB₂ were investigated. First-principles total-energy calculations were used for the analysis. Results showed that high concentration of C impurities can be incorporated in MgB₂ due to its low-formation energies. It was also found that substitutional C impurities lower the formation energies that interstitial C.
