VASP中如何在體系中引入電子和空穴
|
|||
|
各位精通VASP的大蝦們,我剛看到一篇文獻,關于在體系中引入電子和空穴的: Photoexcitation of electron hole pairs in titania results in charge separation, with electrons available to participate in the CO2 reduction. Here, we assume that the dynamics of charge separation is much faster than electron transfer to CO2; therefore the electrons available for reduction are thermalized to the bottom of TiO2 conduction band (CB), which is about 3.8 eV below the vacuum level.17 Photoexcited electrons are modeled by introduction of an extra electron into the system, which populates the conduction band of TiO2. The holes which compensate these electrons and interact with them electrostatically are modeled in three possible ways: (i) completely screened and having no influence (model I); (ii) positive background charge (model II); (iii) localized positive charge in the vicinity,modeled by a proton (model III). J. Phys. Chem. C 2010, 114, 21474–21481 這三個模型是怎么建的???VASP中可以同時引入電子和空穴嗎?好像MS中不可以!沒用過VASP,所以不明白這三個模型是怎么建的。 知道的請解釋一下,不勝感激!俺比較窮,懸賞10個金幣吧^_^ |
