Structural And Electronic Properties

The results of ab initio calculations of the bulk moduli (B0) and related structural and electronic properties of selected transition metals and their nitrides are presented. There is a correlation between B0 and valence charge density. B0 does not vary monotonically with the addition of d electrons. Charge density and density of states (DOS) plots enable us to explain it.

AbstractAtomic resolution high-voltage transmission electron microscopy and electron energy loss spectroscopy were performed on grain boundaries of boron-doped diamond, cooperated with the ab-initio calculation. Segregated boron in the {112}∑3 boundary was caught by the EELS spectra. The change in atomic structure of the segregated boundary was successfully observed from the image by ARHVTEM. Based on the ARHVTEM image, a segregted structure model was proposed.
