利用基于密度泛函理论的线性缀加平面波(LAPW)法, 计算未掺杂和掺杂钨和钒的锐钛矿TiO2晶体的能带和电子态密度. 计算结果表明, 钨和钒的掺杂能够使锐钛矿TiO2的能带明显变窄.

关键词: TiO2, 能带结构, 电子态密度, 线性缀加平面波(LAPW)

The electronic state density and energy bands of doped and un-doped anatase TiO2 were studied by the linearized augmented plane wave method based on the density functional theory. The calculation shows that the energy bands of TiO2 crystals doped with W and V become narrower, resuling in a remarkable red-shift in the absorption spectrum.

Key words: TiO2, band structure, electronic density of states, linearized augmented plane wave
