Abstract

The electronic structure of multi-band dual-gap superconductor magnesium diboride is studied by the linear additive-enhanced plane wave method (LAPW) of density functional theory (DFT). The electron band diagram and density of magnesium diboride are studied. (DOS) and charge density, the electron doping and hole doping of magnesium diboride were studied and analyzed. By replacing the magnesium atom with aluminum atom and replacing the boron atom with carbon atom, the change of charge density is obtained. The changes are explored.
