“…Tunnelling set point parameters used for topographic images and dI/dV maps: Coronene (À1.4 V, 0.7 nA), Au 1 -Coronene (À1.6 V, 0.8 nA). already observed to occur for a trinaphthylene molecule interacting with a single Au atom [9,10]. The two carbon atoms at the end of the phenyl ring interacting directly with the Au atom are moved up together with their corresponding hydrogen atoms.…”

“…It has also been proposed to abandon classical electronic circuit design and to operate Boolean logic operations by only manipulating the electronic quantum states of a single custom designed molecule [7,8]. For example, by using single Au adatoms on a Au(1 1 1) surface as classical logical inputs, a trinaphthylene molecule functions as a NOR logic gate [9,10]. It converts classical On/ Off information per input in quantum information leading to a controlled shift of the trinaphthylene electronic quantum states conforming with a NOR Boolean truth table.…”

“…When molecules are adsorbed on such a surface, the adatoms can interact with and even be trapped by molecules [11][12][13][14][15], leading to characteristic metallic nanostructures that reflect the molecular shape [16][17][18]. In addition to these self-organized structures, manipulation of single adatoms has been used to bring them in contact with molecules [19,20]. So far, real space studies of the molecule-surface interaction have been done mainly under static conditions [21,22] or focus on the lateral diffusion of molecules on surfaces [23][24][25].…”

Observing single-atom diffusion at a molecule-metal interface

The dynamics at the interface between a close-packed porphyrin monolayer and Au(111) is investigated by time-dependent scanning tunneling microscopy, detecting the motion of single-interface adatoms in real space. Imaging sequences reveal predominant switching of the molecular appearance in adjacent molecules, pointing to a spatial correlation that is consistent with adatom diffusion from one molecule to the next. In some cases, the number of switching molecules is drastically increased, indicating collective switching events. In addition to the thermally induced motion of adatoms at the interface, also voltage pulses from the microscope tip can induce the process-revealing different yields in agreement with the model of adatom hopping. DOI: 10.1103/PhysRevB.94.035416 The interface between organic molecules and metal substrates plays a key role for many properties that are important, for instance, in catalytically driven reactions [1,2] and for charge transport [3]. The study of such systems gives detailed insight into fundamental processes that take place at an organic-inorganic interface. For an in-depth understanding, it is advantageous to use a scanning tunneling microscope (STM) for imaging because it provides information about the local environment of each individual molecule, which is important since the molecular properties might differ locallydue to defects, step edges, or different areas of a surface reconstruction [4,5]. For instance, individual C 60 molecules were found to change between dark and bright appearances in STM images, caused by the diffusion of surface [6] or bulk [7] vacancies, charge transfer between molecule and surface [8], or adsorption on small metal islands [9].Adatoms are known to diffuse on close-packed metal surfaces if the thermal energy is sufficient for their detachment from step edges [10]. When molecules are adsorbed on such a surface, the adatoms can interact with and even be trapped by molecules [11][12][13][14][15], leading to characteristic metallic nanostructures that reflect the molecular shape [16][17][18]. In addition to these self-organized structures, manipulation of single adatoms has been used to bring them in contact with molecules [19,20]. So far, real space studies of the molecule-surface interaction have been done mainly under static conditions [21,22] or focus on the lateral diffusion of molecules on surfaces [23][24][25]. Here, we report the dynamic behavior at the molecule-metal interface by observing the motion of individual gold adatoms underneath a molecular monolayer on Au(111) in time.As a molecular system we have chosen tetrabromophenylporphyrin [Br 4 TPP; Fig. 1(a) The appearance of our molecules strongly depends on the applied bias voltage: At −0.5 V all molecules appear at a similar height, while at around −1 V two dark and one bright molecular appearances can be found [ Fig. 1(b)]. The two dark molecules could be identified as two tautomers without a gold adatom, while bright molecules have a single gold adatom underneath, causing the shift i...

“…Similar gold-organic complexes initiated by STM manipulation on surfaces have also been reported elsewhere. [32,36,44,67] In addition, the alkali metals have been successfully attached to organic molecules with the STM tip. [31,33] Formation of metal-ligand coordination between transition metals and organic molecules functionalized with cyano groups has also been achieved on surfaces.…”

Scanning tunneling microscopy (STM) manipulation has received wide attention in the surface science community since the pioneering work of Eigler to construct surface nanostructures in an atom by atom fashion. Lots of scientists have been inspired and devoted to study the surface issues with the help of STM manipulations and great achievements have been obtained. In this Minireview, we mainly describe the recent progress in applying STM manipulations to regulate the inter-adsorbate and adsorbate-substrate interactions on solid surfaces. It was shown that this technique could not only differentiate intermolecular interactions but also construct molecular nanostructures by regulating different kinds of inter-adsorbate interactions or adsorbate-substrate interactions.
