“…PTCDA (3,4,9,10-perylene-tetracarboxylic-dianhydride) and its derivatives have been considered as model systems and have been studied extensively on a wide range of substrates, including metal surfaces [11], semiconductors [12][13][14][15][16], and much more recently graphene substrates [17,18]. Typically, ordered assemblies are stabilized by hydrogen bonds and quadrupole interactions among molecules [19].…”

We have investigated by means of scanning tunneling microscopy (STM) and spectroscopy (STS) the electronic structure of PTCDA (3,4,9,10-perylene-tetracarboxylic-dianhydride) molecular monolayers grown on Au(111). Thanks to our STM/STS measurements, performed under ultra-high vacuum conditions and low temperature, an interface state directly derived from the Shockley-type surface state of pristine Au(111) has been detected. Low bias voltage STM images show the formation of standing wave patterns both on Au(111) and on Au(111) covered by a PTCDA monolayer. These patterns result from the scattering of quasi-free 2D electron surface states with surface defects. By Fourier transforming STM images, the corresponding wavevectors have been extracted. In particular, the simultaneous imaging of both pristine and PTCDA covered Au(111) areas has allowed to measure the Fermi contours and the Fermi wavevectors of both systems. These measurements show that one monolayer PTCDA on Au(111) presents an interface state with an isotropic circular Fermi contour and smaller Fermi wavector ([Formula: see text]) than the corresponding Fermi wavector of pristine Au(111) ([Formula: see text]). This picture is consistent with an upward shift of the Shockley-type surface state due to the presence of the molecular monolayer.

“…PTCDA growth has been investigated on pristine silicon and germanium surfaces, like Si(111), Si(001), Ge(111), and Ge(001), as well as on III–V semiconductor compound surfaces, like GaAs(001) and InSb(001), among others. In the present paper, two prototypical examples that have been studied by STM are reviewed.…”

The application of scanning tunneling microscopy and spectroscopy (STM/ STS) to the study of structural and electronic properties of organic/inorganic systems is presented here. The investigation of PTCDA (3,4,9,10, perylene tetracarboxylic dianhydride, C 24 O 6 H 8 ) on semiconductor or metal surfaces by means of STM/STS shows a wide diversity of results indicating a complex behavior of the PTCDA molecules. It has been found that the surface reactivity highly influences the PTCDA adsorption and growth properties. The degree of molecule-surface interaction can lead to randomly chemisorbed molecules on highly reactive substrates, to one-dimensional row formation on moderately reactive surfaces and well-ordered overlayers in the case of physisorbed PTCDA molecules on weakly reactive surfaces.

“…The presence of insulating film changes the behavior and the electronic structure of the molecules significantly. On bare InSb(001) surface PTCDA molecules spontaneously form molecular wires that are oriented along the [110] crystallographic direction of the substrate surface 31–33. Contrarily, on an ultrathin insulating KBr layer defects of the layer act as adsorption traps, and the formation of molecular wires is hindered 20.…”

Present-day electronic technology, based to a large extent on silicon fabricated devices, is surely approaching size limitations arising from quantum effects. The effort to achieve rapid development of electronic devices requires implementation of entirely new ideas that will allow existing technological constraints to be overcome. Among a wide range of concepts, utilization of single organic molecules, acting as active blocks performing logic operations, appears as one of the most appealing and is based on the state-of-the-art use of modern nanotechnology. In this short review, we offer a selection of recent experiments addressing milestones of single-molecule computing devices technology. Along with discussion of the latest achievements in atomic-and molecular-scale technologies, we discuss their future perspectives, challenges, and still unsolved issues standing in the way of practical implementation of single-molecule devices.Concept of a single-molecule electronic device. The molecule is equipped with various functional groups responsible for logic operations and bonding to an underlying surface and metallic nanoelectrodes. The monomolecular nanodevice is deposited on a thin buffer layer assuring the decoupling from a (semi-)conducting substrate.
