Structural reorganization of carbon nanoparticles into single-wall nanotubes

Physical review. B, Condensed matter (2002)

R. Larciprete Silvano Lizzit S. Botti Cinzia Cepek A. Goldoni

The structural reorganization of carbon nanoparticles into single-wall nanotubes via high temperature annealing in absence of metal catalysts, was monitored by photoemission and x-ray absorption spectroscopy. It has been found that for this system an advanced graphitization process is made possible by the peculiar nanoparticle internal structure containing extended ${\mathrm{sp}}^{2}$ coordinated domains with a sizable degree of ordering. Possible mechanisms for the formation of nanotubes via self-assembling of carbon aggregates are discussed.

Mechanism of CO Intercalation through the Graphene/Ni(111) Interface and Effect of Doping

The Journal of Physical Chemistry Letters (2020)

Daniele Perilli Sara Fiori Mirco Panighel Huan Liu Cinzia Cepek

Molecules intercalate at the graphene/metal interface even though defect-free graphene is impermeable to any atomic and molecular species in the gas and liquid phase, except hydrogen. The mechanism of molecular intercalation is still a big open question. In this Letter, by means of a combined experimental (STM, XPS, and LEED) and theoretical (DFT) study, we present a proof of how CO molecules succeed in permeating the graphene layer and get into the confined zone between graphene and the Ni(111) surface. The presence of N-dopants in the graphene layer is found to highly facilitate the permeation process, reducing the CO threshold pressure by more than one order of magnitude, through the stabilization of multiatomic vacancy defects that are the open doors to the bidimensional nanospace, with crucial implications for the catalysis under cover and for the graphene-based electrochemistry.

Graphene islands mixed to carbon nanostructures grown on TiN film: A multi-techniques characterization approach

physica status solidi (b) (2012)

Sunil Bhardwaj Manvendra Kumar Carla Castellarin Cudia M. Pedio Cinzia Cepek

Abstract By using a variety of experimental techniques, we were able to reveal the presence of few percent of well‐ordered graphene islands mixed to disordered carbon, isolated carbon tubes, and flakes. The sample were synthesized on a metallic TiN film using catalytic chemical vapor deposition and characterized by scanning electron microscopy, Raman spectroscopy, and K‐resolved inverse photoemission spectroscopy. Because of the metallic TiN support and the presence of well‐ordered one or two layers graphene islands, the so grown carbon nanostructures (CNs) can be used in many applications. Our results indicate that a multi‐techniques approach is fundamental to fully characterize CNs.

Surface phase transitions of Ge(100) from temperature-dependent valence-band photoemission

Physical review. B, Condensed matter (1998)

A D Laine M. De Seta Cinzia Cepek S. Vandrè A. Goldoni

Valence-band photoemission at a photon energy of 32 eV has been carried out on Ge(100) from below room temperature to 1173 K. The $c(4\ifmmode\times\else\texttimes\fi{}2)\ensuremath{\rightarrow}2\ifmmode\times\else\texttimes\fi{}1$ phase transition is accompanied by a shifting of a back-bond-derived surface state. The high-temperature $2\ifmmode\times\else\texttimes\fi{}\stackrel{\ensuremath{\rightarrow}}{1}1\ifmmode\times\else\texttimes\fi{}1$ transition is apparent in the discontinuity in the measured emission intensity of both a bulk and a surface electronic state. A further discontinuity occurs in both of these features and of the Fermi level intensity at higher temperature, approximately 1075 K, indicating the presence of a further reversible phase transition whose nature is discussed.
