| Popis: | In this study, the concept of barium diboride as a special kind of superconductor was investigated based on its structural arrangement that is able to trigger charge reservoir than the acclaimed magnesium diboride. The structural analysis of barium diboride shows that it has two kinds of undulation that depicts it has both bonding and antibonding Fermi surface. The implication of this scenario is the possibility of an intermingled Fermi level. The sizes of the multiphase (hexagonal and orthorhombic) are between 11 and 53.4 nm. The orthorhombic phase of the crystal system has Debye-Waller factor and particle size of 41.51 and 26.9 nm, respectively. It was observed from the density function theory calculations that the rates of transitions of the Cooper pairs are strongly dependent on the electron–phonon interaction. The barium atom is more active in the conduction band at |
