Charge states and distribution of iron ions in polycrystalline cubic boron nitride
Abstract The local electronic states and distribution of 57 Fe ions in cubic boron nitride (c-BN) polycrystals as a function of technological processing were investigated. The study has been performed on c-BN samples prepared by catalytic synthesis and by direct phase transformation.

Synthesis of Boron-Aluminum Nitride Thin Film by Chemical Vapour Deposition Using Gas Bubbler
Boron included aluminium nitride (B-AlN) thin films were synthesized on silicon (Si) substrates through chemical vapour deposition ( CVD ) at 773 K (500 °C). tert-buthylamine (tBuNH2) solution was used as nitrogen source and delivered through gas bubbler.
