Carbon nanocapsules were manipulated inside a high-resolution transmission electron microscope and assembled into single-nanocapsule junctions sandwiching between two gold electrodes. The electric conductivity was measured simultaneously with the lattice imaging of structural dynamics. It was found that the differential conductance of the junction at bias voltages from 0 to 0.20 V corresponded to half of quantized conductances, i.e., 0.5G 0 where G 0 =2e 2 / h is the conductance quantum, e is the electron charge, and h is Planck's constant. At bias voltages larger than 0.20 V, the interface structure between the capsule and the electrode changed and the differential conductance increased to 1G 0 . The study showed that carbon nanocapsule junctions are quantized conductors.

“…The spectrum of the trace line includes more carbon and less oxygen than the Si substrate, and so it means that the trace line must originate from the C 60 nanowhisker. Such a framework of the C 60 nanowhisker seems to be retained after a heat treatment at 800 ο C, which may be a fullerene shell tube [8]. , × 2000).…”

“…On the other hand, with respect to the thermal properties of C 60 nanowhiskers, the heated fullerene nanowhiskers could get a high specific surface area and a high electrical conductivity [5]. Asaka et al examined the electrical conductivity of a C 60 whisker preheated in vacuum at 1100 °C in a TEM [6].…”
