Summary: This study demonstrates the nanoscale mapping of carrier mobilities in carbon nanotube networks, revealing variations in charge transport behaviors depending on network structures. By using scanning noise microscopy, the spatial distribution of localized charge transport properties such as mobilities and charge trap densities are successfully mapped, and the correlations between mobility/conductivity and charge trap density are analyzed to determine charge transport mechanisms. This research is of great significance for both fundamental research and practical device applications.

Summary: This study characterizes the adsorption, self-assembly, and electronic structure of [5,5]-C-90 fullertube molecules on different noble metal surfaces using scanning tunneling microscopy and spectroscopy. The results show that the shape of the molecular orbitals of the adsorbed fullertubes matches the theoretical calculations, and some of the molecular orbitals are influenced by the quantum confinement imposed by the hemifullerene caps. These findings provide a conceptual framework for the design and understanding of custom fullertube molecules.

Summary: The electrical conductivity of macroscopic assemblies of nanomaterials is determined by the interplay between electronic transport and phonons. Phonons can reduce conductivity through electron scattering, but also enhance it by aiding electron propagation. In this study, we found that phonon-assisted coherent electron transport is the dominant mechanism for high-temperature transport in carbon nanotubes. This discovery proves the potential of single-chirality carbon nanotube films as unique solid-state ensembles for the development of room-temperature coherent electronic devices.
