    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...

    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...

    STM “Tip Changes” — A Possible Tool for Tip Characterization

    A method based on the detailed analysis of STM tip changes is proposed for the investigation of tip cluster structure. As proposed by Mizes et al [2] the tunneling current for a multiple tip is considered to b...
