Figure 3: Schematic representation of the arrangement of the Alq3 molecules on the Co surface.
From: Dynamic spin filtering at the Co/Alq3 interface mediated by weakly coupled second layer molecules
For a nominal coverage of one ML, we distinguish between molecules in direct contact with the Co surface (first layer) and molecules that are far away from Co and thus are weakly coupled (second layer). Here we display the supercell describing the first and second layer of the Co/Alq3 interface (periodically repeated three times along one direction for better display). The nitrogen atoms in the ligands of the physisorbed Alq3 molecule are labelled N’1, N’2 and N’3 for future reference. Colour code for the Co/Alq3 interface: Co (grey), Al (purple), C (yellow), O (red), N (dark blue) and H (cyan).
