Abstract

We performed the ultraviolet photoemission spectroscopy study of single-walled carbon nanotubes (SWCNTs) encapsulating C₅₉N. The work function of the C₅₉N@SWCNT is estimated to be larger than that of the SWCNT. The π states of the SWCNT shift toward the Fermi level upon encapsulation of C₅₉N. The C₅₉N pea spectrum is roughly similar to that of the (C₅₉N)₂, but some peaks shift. The results suggest a small charge transfer from the SWCNT to the C₅₉N pea, which is in contrast to the previously reported n-type FET characteristics. This discrepancy is probably due to the difference in the molecular form of C₅₉N.
