    Different sensing mechanisms in single wire and mat carbon nanotubes chemical sensors

    Chemical sensing properties of single wire and mat form sensor structures fabricated from the same carbon nanotubes (CNT) materials have been compared. Sensing properties of CNT sensors were evaluated upon ele...

    Ion irradiation effects on conduction in single-wall carbon nanotube networks

    We have measured how irradiation by Ar+ and N+ ions modifies electronic conduction in single-wall carbon nanotube (SWNT) networks, finding dramatically different effects for different thicknesses. For very thin t...

    INFLUENCE OF CATALYST AND CARBON SOURCE ON THE SYNTHESIS OF CARBON NANOTUBES IN A SEMI-CONTINUOUS INJECTION CHEMICAL VAPOR DEPOSITION METHOD

    The injection chemical vapor deposition (CVD) method allows the semi-continuous production of pure multi-wall carbon nanotubes (MWCNTs). In order to find the most efficient catalyst material and carbon source,...

    Modeling and Interpretation of STM Images of Carbon Nanosystems

    Scanning tunneling microscopy (STM) is the only tool making it possible to study both the topography and electronic structure of carbon nanosystems in sub-nanometer resolution. The interpretation of the STM im...

    Y-branching of single walled carbon nanotubes

    Y-branching was observed by scanning tunnelling microscopy (STM) in single wall carbon nanotubes grown by thermal decomposition of C60 fullerene in the presence of transition metals. These novel carbon nanostruct...

    Scanning Probe Microscopy (STM, AFM) Investigation of Carbon Nanotubes

    The image formation in scanning tunneling microscopy (STM), atomic force microscopy (AFM), and the particularities of imaging supported carbon nanotubes by STM and AFM are discussed. The milestones of STM, STS...
