Intrinsic molecular fluorescence from porphyrin molecules on Au(100) has been realized by using a nanoscale multimonolayer decoupling approach with nanoprobe excitation in the tunneling regime. The origin of luminescence is established observed well-defined vibrationally resolved spectra. fluoresce at low "turn-on" voltages for both bias polarities, suggesting an mechanism via hot electron injection either tip or substrate. excited decay radiatively through Franck-Condon pi(*)-pi transitions.
The influence of cryothermal treatment on the mechanical properties metallic glasses with different compositions was investigated in present work. It found that cycling can induce rejuvenation as well relaxation glasses. local apparent Young’s modulus and its spatial distribution width surface glass increase after cycling, while bulk effect depends composition. appeared this is temporary disappears a period room temperature aging. This connected large times due to their heterogeneous...
A control system for the laser interferometer reactive ion etching setup was developed. series of chips with same structure were fabricated precise calibration upper silicon layer silicon-on-insulator material rate. The thickness on each chip varied depending time. height resulting steps measured using semicontact mode an atomic force microscope. For regime in CF4 and O2 gas plasma (flow ratio 20:5, pressure 4 Pa, power 40 W), rate is 0.31 ±0.1 nm/s. adduce parameters allow stopping at a...
Well-ordered arrays of Fe3O4 nanoparticleswith a new type packing have been produced using the Langmuir–Blodgett technique. Depending on local absorption conditions, both 2D and 1D assemblies nanoparticles are produced, latter in form single double chains equally spaced nanoparticles. The Figure depicts film stearic acid monolayer.
This work is the result of coherent effort a multi-disciplinary research team working for considerable number years in former USSR area nanocluster molecular electronics. For first time successful demonstration single-electron tunnelling transistor reliably at room temperature and based on single metallorganic cluster presented. A broad spectrum different clusters was investigated. Our group has developed complete cycle custom-designed manufacturing, deposition, characterization modification...
Morphology evolution of the multicomponent metallic glass film obtained by radio frequency (RF) magnetron sputtering was investigated in present work. Two modes were distinguished: smooth mode and clustered mode. The parameters, which have most influence on modes, determined. As a result, amorphous Ni-Nb thin films with surface nanoglassy structure deposited silica float Si substrates. phase composition target appeared to significant chemical film. differences charge transport nanomechanical...
Here we present an original CMOS compatible fabrication method of a single-electron transistor structure with extremely small islands, formed by solitary phosphorus dopants in the silicon nanobridge. Its key feature is controllable size reduction nanobridge sequential cycles low energy isotropic reactive ion etching that results decreased number active charge centers (dopants) from hundreds to single one. Electron transport through individual phosphorous lattice was studied. The final...
Here, we report on the properties of native and artificial oxide amorphous thin film a surface an Ni-Nb sample. Careful measurements local current-voltage characteristics system / NiNb oxide/Pt, were carried out in contact mode atomic force microscope. Native showed n-type conductivity, while one exhibited p-type one. The shape characteristic curves is unique both cases no analogical behavior found literature. X-ray photoelectron spectroscopy (XPS) used to detect chemical composition films...
Abstract Shear-induced segregation, by particle size, is known in the flow of colloids and granular media, but unexpected at atomic level deformation solid materials, especially room temperature. In nanoscale wear tests an Fe-based bulk metallic glass temperature, without significant surface heating, we find that intense shear localization under a scanned indenter tip can induce strong segregation dilute large-atom solute (Y) to planar regions then crystallize as Y-rich solution. There...
A room temperature single-electron transistor based on the single cluster molecule has been demonstrated for first time.Scanning tunneling microscope tip was used to study transport via carboran 1,7-(CH 3 ) 2 -1,2-C B 10 H 9 Tl(OCOCF incorporated into Langmuir-Blodgett monolayer of stearic acid.DC I-V curves at 300 K showed well pronounced Coulomb staircase, and current could be controlled by a lithographically fabricated gold gate electrode.73.
Molecular luminescence from an ultrathin layer of free-base porphyrin molecules has been generated by a scanning tunneling microscope on top monolayer spacer perinone derivatives Cu(100). Tunneling-electron-induced fluorescence spectra are in good agreement with the conventional photoluminescence data molecule. The dominant molecular peak becomes clear and sharp for bias voltages above ∼2.1 V. does not emit light because quenching effects; it acts as buffer to enhance decoupling electronic...
We present the original method for fabricating a sensitive field/charge sensor based on field effect transistor (FET) with nanowire channel that uses CMOS-compatible processes only. A FET kink-like silicon was fabricated from inhomogeneously doped insulator wafer very close (∼100 nm) to extremely sharp corner of chip forming local probe. The single e-beam lithographic process shadow deposition technique, followed by separate two reactive ion etching processes, used define narrow...
