    a lot of short MWNTs were found close to the surface of the support, which is more clearly shown in Figure 1f. Since we cannot find such tubular carbonaceous impurities in Figure 1c, which shows the surface of the raw materials from Co/MgO catalysts, it was highly possible that such short MWNTs resulted from the Mo addition.

    Electrical breakdown of short multiwalled carbon nanotubes .

    Electrical breakdown of short (∼50nm) multiwalled carbon nanotubes (MWNTs) is studied utilizing mechanically controllable break junction technique with gold electrodes. Measurements of the conductance-bias characteristics near the breakdown point revealed two different types of breakdown behavior for the short MWNTs. In one type designated as type I, the conductance increases nearly …
