title = "High energy-resolution EELS study of the electronic structure of boron nitride cones",
abstract = "Electron energy-loss spectra were obtained from a single boron-nitride cone (BN cone) with an apex angle of 20 degrees, which is made of curved BN layers. The spectra obtained from the tip region showed the π plasmon peak at 7.4 eV, which is smaller than that of bulk hexagonal boron-nitride (h-BN) composed of flat BN layers. The smaller π plasmon energy indicates that the bandgap energy of the BN cone is smaller than that of h-BN. The intensity distribution of the π+σ plasmon peak is explained by the surface loss-function. The B K-shell electron excitation spectra were obtained from the bottom edge region. The spectra showed additional peak intensity compared with that of bulk h-BN.",
