Density functional theory study of Al-doped hematite

Density functional theory study of Al-doped hematite

Using first-principles density functional theory calculations within the generalized gradient approximation (GGA) as well as the GGA+U approach, we study Al-doped ?-Fe 2O 3 crystals. Structural, electronic, magnetic and optical properties due to impurity incorporation have been investigated and disc...
