Tip-induced deformations of meso-(4-cyanophenyl)-substituted Zn(II) porphyrin molecular wires self-assembled on KBr(001) were studied by frequency modulation dynamic force microscopy. Since the wires are weakly bonded to the KBr substrate and to the neighboring molecules, they can easily be cut by the scanning tip. We found that the damaged molecular wires self-healed at room temperature.

    Significant reduction in inhomogeneous broadening of GaAs/AlGaAs V-groove quantum wires (QWRs) is achieved by growing them on vicinal (001) GaAs substrates misaligned by several degrees with respect to the [formula] groove direction. Low temperature photoluminescence spectra exhibit QWR...

    Ag-assisted anisotropic lateral etching along the <100> directions in Si nanowire arrays (Si NWAs) is investigated. It is found that Ag ions, generated by H2O2 oxidation of Ag particles, re-nucleate on the sidewalls of the nanowires, causing side etching and tapering of the wires. By enhancing...

    Relying on Frenkel Kontorova (FK) models of diatomic chains of increasing levels of complexity, this study presents an overall view of the diversity of structural effects that a compound (oxide) chain supported on a metal may display and helps assigning them to precise microscopic mechanisms. At...

    We have used a combined dynamic scanning tunneling and atomic force microscope to study the organization of weakly bound adsorbed molecules on a graphite substrate. These weakly bound molecules may be imaged in dynamic scanning tunneling microscopy (STM) mode in which the probe is oscillated...

    We demonstrate ordered array formation of Au nanoparticles by controlled solid-state dewetting of a metal film on stepped alumina substrates. In situ transmission electron microscopy studies reveal that the dewetting process starts with nucleation of ordered dry regions on the substrate. The...

    We demonstrate that it is possible to distinguish two conductance switching mechanisms in silver sulfide devices at room temperature. Experiments were performed using a Ag2S thin film deposited on a wide Ag bottom electrode, which was contacted by the Pt tip of a scanning tunneling microscope....

    Indium tin oxide nanowires have been grown by dc sputtering on different substrates without the use of catalysts or oblique deposition. The nanowire length was of the order of several μm, while their diameter was ∼50-100 nm. Small side branches on the nanowires were frequently observed....

    We investigate electron transport through a mono-atomic wire which is tunnel coupled to two electrodes and also to the underlying substrate. The setup is modeled by a tight-binding Hamiltonian and can be realized with a scanning tunnel microscope (STM). The transmission of the wire is obtained...
