Silica (SiO 2) bonded porous silicon nitride (Si 3 N 4) ceramics were fabricated from α-Si 3 N 4 powder in air at 1200–1500 °C by the oxidation bonding process. Si 3 N 4 particles are bonded by the oxidation-derive SiO 2 and the pores derived from the stack of Si 3 N 4 particles and the release of N 2 and SiO gas during sintering. The influence of the sintering …

Microscopic modeling of the dielectric properties of silicon nitride
We investigate the differences between the dielectric properties of bulk silicon nitride and thin films, in both crystalline and amorphous structures. We show that to correctly account for the decrease of the optical (${ensuremath{epsilon}}_{ensuremath{infty}}$) and static (${ensuremath{epsilon}}_{0}$) dielectric constants at the nanoscale, it is necessary to …
