Ellipsometric investigation of β-Si₃N₄ ceramics with Mo and Al additives
Ceramic Si₃N₄ samples with Мо and AI admixtures have been investigated by spectroellipsometry. The influence of admixtures on the ceramics optical properties have been studied. The local defects of Si₃N₄ crystal structure are responsible for the band gap reduction. The silicone oxynitride amount in...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Ceramic Si₃N₄ samples with Мо and AI admixtures have been investigated by spectroellipsometry. The influence of admixtures on the ceramics optical properties have been studied. The local defects of Si₃N₄ crystal structure are responsible for the band gap reduction. The silicone oxynitride amount in the studied samples has been estimated numerically by Bruggeman effective medium approximation. |
