Investigation of Intra-Nitride Charge Migration Suppression in SONOS Flash Memory
Micromachines, 2019 In order to suppress the intra-nitride charge spreading in 3D Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) flash memory where the charge trapping layer silicon nitride is shared along the cell string, N2 plasma treated on the silicon nitride is proposed ...

Compact silicon nitride interferometers
Optics Express, 2023 We demonstrate a compact silicon nitride interferometer which uses waveguides with the same length and different effective indices instead of similar effective indices and different lengths. In such structures there is no need to have waveguide bends.

Nonoxide Sol-Gel Synthesis of Terbium-Doped Silicon Nitride Phosphors
, 2009 Exposure of solutions of Tb(N(SiMe3)2)3 with SiCl(NEt2)3 in tetrahydrofuran to dry ammonia results in polymeric xerogels. Heating these gels in ammonia leads to amorphous Tb:SiNx phosphors that exhibit bright green luminescence under UV irradiation.
