The ultrasoft pseudopotential planewave (UPPW) within density functional theory (DFT) has
been used to investigate the electronic structure, optical, elastic and thermodynamics …

Si-doped cubic boron nitride (c-BN) is synthesized at high pressure and high temperature,
and the local environment of Si is investigated using X-ray absorption near edge structure …

Be-doped cubic boron nitride (cBN) crystals were synthesized under high pressure and high
temperature. Be atom was doped into the crystals by mixing of Be metal to the growth …

This dissertation focuses on the behavior of rare-gas atoms on metal surfaces, which have a
long tradition in serving as model systems in condensed matter physics. Furthermore, rare …

Impurity-induced modes at 212 and 535cm 1 have been studied by using Raman scattering
spectroscopy in Be-doped cubic boron nitride single crystals, which have been grown by the …

The cathodoluminescence and photoluminescence spectra of cubic boron nitride doped
with beryllium under high-pressure and high-temperature conditions are investigated. It is …

Ab initio calculations on hydrogen complexes with Mg and Be impurities in c-BN are
reported. We find that both impurities are acceptors and both bind H to form passive defects …

The Raman spectra of single crystals of cubic boron nitride (cBN) doped with beryllium and
also synthesized in the absence of dopants are investigated. It is shown that the wide bands …

The density of states and the band diagrams were computed for diamond, cubic boron nitrde
(cBN), and hexagonal boron nitride (hBN) using a Korringa-Kohn-Rostoker (KKR) scheme to …

Ab initio calculations on hydrogen complexes with Mg and Be impurities in c-BN are
