Research Abstract

Base on transmission electron microscopy technique, high-quality specimen areas were examined by using CBED, EELS and SXES methods. Characteristic electronic states of boron nano-belt, zeolite-templated carbon, polymerized C_<60>, Li-doped α-rhombohedral boron and MgB_4 were revealed. Improvements of anisotropic valence charge density analyses by CBED and SXES, and optical properties of nano-partucles by EELS were also done.
