Mgo type of crystalline structure
Webb26 juli 2024 · Here, we report the fabrication of high-quality, large-area, single-crystal graphene on crystalline magnesium oxide (MgO), which has a dielectric constant of 7–10. Magnesium and oxygen are intercalated at the interface of epitaxial graphene/Ru (0001) and form crystalline structure after high-temperature annealing. WebbThe structure and changes occurring during the volume crystallization of a MgO-Al 2 O 3 -SiO 2 -TiO 2 glass induced by heat-treatment at temperatures in the range 740 to 1300° C were investigated by means of DTA, scanning electron microscopy, X-ray diffraction, electron microprobe analysis, density and other measurements.
