Fabrication of C60-Cox using atom and molecule manipulation
Peng YANG, Jérôme LAGOUTE, Vincent REPAIN, Cyril CHACON-CARILLO, Yann GIRARD and Sylvie ROUSSET Laboratoire Matériaux et Phénomènes Quantiques, Université Paris Diderot et CNRS, UMR 7162 Understanding of the electronic process at the interface and the interac2on between the organic molecule and metal at atomic/molecular scale is cri2cal to build the new genera2on molecule electronic devices. Moreover, atom manipula2on using scanning tunneling microscopy (STM) allows the forma2on of atomic controlled ar2ficial molecule-‐ metal conjugate. Using a low temperature (LT) STM and scanning tunneling spectroscopy (STS), we manipulate atoms and molecules to build C60-‐Cox complex and study its physical proper2es.

Conclusion • Two methods to build the C60-‐Cox by atomic and molecular manipula2on • XMax = 9 • The molecule and complexe can be moved or rolled on the surface • The molecular orbitals are shiLed by adding Co atoms to C60 • Conductance maps show similar molecular orbitals for C60 and C60-‐Cox
