As a result, electronic bands, total and site-projected l - decomposed DOS at the Fermi level, shape of the Fermi surface for Nb2InC were obtained for the first time. Besides, independent elastic constants, bulk modulus, compressibility, shear modulus, Young's modulus, Poisson's ratio together with the elastic anisotropy parameters and indicator of brittle/ductile behavior of Nb2InC were evaluated and analyzed in comparison with the available data |
