In-Plane Intermolecular Interaction Assisted Assembly and Modified Electronic States of Metallofullerene GdC₈₂

Orientational configuration and electronic states of GdC82 bonding to Cu(111) have been thoroughly investigated by low-temperature scanning tunneling microscopy/spectroscopy (LT-STM/S) and differential conductance mapping complemented by first-principles calculations. We clarify that individual Gd@C...

520 |a Orientational configuration and electronic states of GdC82 bonding to Cu(111) have been thoroughly investigated by low-temperature scanning tunneling microscopy/spectroscopy (LT-STM/S) and differential conductance mapping complemented by first-principles calculations. We clarify that individual Gd@C82 energetically adopts tilting adsorption configuration with the scanning tunneling spectroscopy (STS) states readily assigned to the C82 cage/Cu(111) hybrid states and the Gd/cage hybrid states, respectively. Moreover, upon assembling and sufficient thermal activation, Gd@C82 fullerenes are inclined to restore the energetically favored tilting orientational configuration similar to an individual one. This suggests the feasibility of high-level integration of single-Gd@C82 based moletronic device with the performances almost unchanged by two-dimensional arrangement. Furthermore, by rationalizing the inter-Gd@C82 interaction induced slight energy offset of the electronic states, we qualitatively confirm the shown electronic hybrid states as Cu(111)-, C82 cage- and Gd-dominant hybrid states, respectively
