Intercalation of metals and silicon at the interface of epitaxial graphene and its substrates 下载免费PDF全文
Intercalations of metals and silicon between epitaxial graphene and its substrates are reviewed. For metal intercala- tion, seven different metals have been successfully intercalated at the interface of graphene/Ru(O001) and form different intercalated structures. Meanwhile, graphene maintains its original high quality after the intercalation and shows features of weakened interaction with the substrate. For silicon intercalation, two systems, graphene on Ru(O001) and on Ir(l I 1), have been investigated. In both cases, graphene preserves its high quality and regains its original superlative properties after the silicon intercalation. More importantly, we demonstrate that thicker silicon layers can be intercalated at the interface, which allows the atomic control of the distance between graphene and the metal substrates. These results show the great potential of the intercalation method as a non-damaging approach to decouple epitaxial graphene from its substrates and even form a dielectric layer for future electronic applications. 相似文献

Three different methods are used to manipulate and control
phthalocyanine based single molecular rotors on Au (111)
surface: (1) changing the molecular structure to alter the
rotation potential; (2) using the tunnelling current of the scanning
tunnelling microscope (STM) to change the thermal equilibrium of the
molecular rotor; (3) artificial manipulation of the molecular rotor
to switch the rotation on or off by an STM tip. Furthermore, a
molecular `gear wheel' is successfully achieved with two
neighbouring molecules. 相似文献
