Abstract. The current–voltage characteristics of individual cup-stacked carbon nanotubes (CSCNTs) were investigated in situ inside the transmission electron microscope. Different from other quasi-1D carbon structures such as multi-walled carbon nanotubes, carbon nanofibers or graphitic fibers that normally behave as a metallic conductor of electrons, individual CSCNTs were found to exhib…
Extraordinary and stable long wavelength emission centered at 685 nm from the yard-glass shaped boron nitride nanotubes YG-BNNTs was observed in their cathodoluminescence and photoluminescence spectroscopy. The mechanism for this near-red light emission at 685 nm is attributed to the periodical nature of the BNNT units with regular lattice defects. The visible-light emission from YG-B…
