从DFT +U计算重新分配金红石TiO_2(110)的(1 × 2)重构

Re-assigning (1x2) reconstruction of rutile TiO_2(110) from DFT+U calculations

Hatice Ünal, Ersen Mete, Şinasi Ellialtioğlu

摘要:

采用密度泛函理论(DFT)和Hubbard U在位库仑排斥(DFT+U)方法研究了金红石型TiO 2(110)-(1x 2)表面的电子结构.比较了Onishi提出的两种主要的重构模型--岩泽和Park等的热力学稳定性。

英文摘要:

Physically reasonable electronic structures of reconstructed rutile TiO_2(110)-(1x2) surfaces were studied using density functional theory (DFT) supplemented with Hubbard U on-site Coulomb repulsion acting on the d electrons, so called as the DFT+U approach. Two leading reconstruction models proposed by Onishi--Iwasawa and Park et al. were compared in terms of their thermodynamic stabilities.
