Abstract Experimental observations indicate that removing bridging oxygen atoms from the TiO2 rutile (110) surface produces a localised state approximately 0.7 eV below the conduction band. The corresponding excess electron density is thought to localise on the pair of Ti atoms neighbouring the vacancy; formally giving two Ti3+ sites. We consider the electronic structure and geometry of the oxygen deficient TiO2 rutile (110) surface using both gradient-corrected density functional theory (GGA DFT) and DFT corrected for on-site Coulomb interactions (GGA + U) to allow a direct comparison of the two methods. We show that GGA fails to predict the experimentally observed electronic structure, in agreement with previous uncorrected DFT calculations on this system. Introducing the +U term encourages localisation of the excess electronic charge, with the qualitative distribution depending on the value of U. For low values of U (64.0 eV) the charge localises in the sub-surface layers occupied in the GGA solution at arbitrary Ti sites, whereas higher values of U (P4.2 eV) predict strong localisation with the excess electronic charge mainly on the two Ti atoms neighbouring the vacancy. The precise charge distribution for these larger U values is found to differ from that predicted by previous hybrid-DFT calculations 帮助翻译下摘要吧,自己翻译的牛头不对马嘴,另外翻译的大神有没有这篇文章的完整翻译,有的话提供下,不胜感激,文章题目: A DFT + U description of oxygen vacancies at the TiO2rutile (1 1 0) surface [ Last edited by xiaoyaobeiji on 2013-4-1 at 09:37 ] |

初来乍到,不知道情况,金币我目前只有这么点,要多少才可以呢?可不可以分期付款啊,额,刚才那个是玩笑,不过我真不知道价钱,多少金币,出个价,金币我想办法,后期追加。或者修改价格都行
