摘要: The 1s core-level absorption spectra of the sp3 bonded carbon (cubic and hexagonal polymorphs) boron nitrides (zincblende wurtzite were calculated using an ab initio pseudopotential plane wave method including core-hole effects. A comprehensive comparison with available experimental data shows that there exist characteristic features can be used to spectroscopically identify different polymorphs. anisotropic characters K-edge in diamond nitride provide additional phase specific signatures. application spectroscopic fingerprinting identification these metastable phases is discussed.
