A plane wave density functional theory method was used to investigate the adsorption properties of isolated alkali metal atoms, including Li, Na, K, Rb and Cs on-top of the F 0 s defective center of MgO(001) surface. Among all the alkali metals, the lithium atom binds most strongly with the highest adsorption energy of 0.67 eV and the shortest distance of about 0.257 nm between metal and the surface, the binding energy for the sodium atom comes second, and just half of this value for the other alkali metal ... 相似文献

Representing new states of quantum matter, topological insulators are characterized by an insulating gap in the bulk state and a robust metallic surface or edge state protected by time-reversal symmetry. Topological surthce states have been theoretically predicted and experimentally observed in three-dimensional materials such as A2B3-type compounds of Bi2Se3, Bi2Te3, and Sb,Te3. Similar to topological insulators, 相似文献
