Effects of Surfactants and Surface Treatment on Aqueous …

The effects of the addition of surfactants and of the surface treatment upon the aqueous dispersion of silicon carbide were examined. In the case of β-SiC, the addition of nonionic surfactants having relatively longer lengths of hydrocarbon and oxyethylene chain to the β-SiC treated with a silane coupling agent enhanced the dispersion stability.

Electrically driven optical interferometry with spins in …

Here, we demonstrate electrically driven coherent quantum interference in the optical transition of single, basally oriented divacancies in commercially available 4H silicon carbide. By applying microwave frequency electric fields, we coherently drive the divacancy’s excited-state orbitals and induce Landau-Zener-Stückelberg interference fringes in the resonant optical absorption spectrum.
