Studies on optical transmittance of boron-doped nanocrystalline diamond films

Abstract

Thickness is one of the most important parameters in many applications using thin layers. This article describes determination of the thickness of boron-doped nanocrystalline diamond (NCD) grown on fused silica glass. The spectroscopic measurement system has been used. A high refractive index (2.3 @ 550 nm) was achieved for NCD films. The thickness of the NCD samples has been determined from transmission spectrum. Full Text: PDF ReferencesZ. Li, S. Butun, K.
