| 1. | Further investigations show that new surface states are derived by the doping , which may lead to the changes of the surface properties of sno _ 2 ( 110 ) . it seems that the type of doping atom has great effects on the positions of doping states 值得注意的是, ti掺杂对co吸附影响较小,而掺杂ru原子可显著增强表面对co的吸附,尤其是五配位sn原子被ru取代后,具有最大的吸附能。 |
