Electron Energy Loss Spectroscopy of Amorphous Boron Filaments

概要

Electron energy loss spectroscopy has been used to investigate the B-K spectra of individual filaments grown by electron beam irradiation. We also measured the energy loss spectra of β-rhombohedral boron and B_4C for reference. High-resolution transmission electron microscope images, micro-electron diffraction patterns, and elemental analysis by energy loss spectra revealed that the filaments consist of amorphous boron. The similarity of B-K near-edge structures between the filaments and the reference forms of boron suggests that the filaments have B_<12> icosahedra as their basic structural unit, which is consistent with previous structural studies of amorphous boron. The different peak sharpnesses just above the B-K edge may reflect differences in structural complication and/or disorder of B_<12> icosahedron units.
