“…Hence ELNES probes the local density of unoccupied electronic states. Calculations of ELNES using selfconsistent band theory methods 12,13 and multiple scattering theory [14][15][16] show reasonable overall agreement with available experimental spectra. Specifically, the ELNES of c-BN has been presented by many authors, both theoretically 12,15,16 and experimentally.…”

A comparison between experimental and theoretical electron Energy Loss Near Edge Structure (ELNES) of B and N K-edges in cubic boron nitride is presented. The electron energy loss spectra of cubic boron nitride particles were measured using a scanning transmission electron microscope. The theoretical calculation of the ELNES was performed within the framework of density functional theory including single particle core-hole effects. It is found that experimental and calculated ELNES of both the B and N K-edges in cubic boron nitride show excellent agreement.

“…Similar results were observed in energy-loss near-edge structures (ELNES) of carbon, aluminum, and nitrogen K-edges (Figure b–d). The recorded ELNES spectra in the vicinity of the diamond/AlN heterointerface have shown the typical C, Al, and N K-edge structures that have been previously reported for bulk diamond and AlN materials in the literature, − confirming a high-quality crystalline heterointerface.…”

We have investigated the growth and atomic interface structures of diamond on aluminum nitride (AlN). The two-step chemical vapor deposition technique is used to control diamond nucleation density, crystal size, and AlN surface orientation and polarity. Highly uniform diamond layers with a nucleation density in the range of 10 5 −10 11 cm −2 and a grain size of 0.1−5 μm are fabricated. Crystallographically abrupt interfaces between polycrystalline diamond and single-crystal AlN(0001) layers have been observed via high-resolution transmission electron microscopy and electron energy-loss spectroscopy. A majority of the diamond crystals have been found to have the diamond(111)/AlN(0001) interface relationship. Atomistic models of the bonding mechanism at the heterointerface are used to elucidate experimental observations and the role of hydrogen plasma on the growth of diamond on AlN. Nonpolar and semipolar AlN surfaces have been found to have higher resistance to process plasma and led to better crystallinity of the diamond/AlN heterointerfaces. These results underline the potential of nonpolar and semipolar AlN surfaces for the growth of high-crystal quality diamond/AlN heterointerfaces.

“…The comparison between SiCN and reference data evidences that the local environment around N-atoms in ABSE and HVNG-derived ceramics is essentially the same of N-atoms in Si 3 N 4 . EELS investigations performed on N-doped carbon compounds [32][33][34] showed that C-N bonds are characterized by p * and r * peaks located at 399 and 408 eV, respectively. None of these characteristic features can be recognized in the present spectra.…”
