    Safety

  • Packaging Under

    Nitrogen
  • Volatile Carbosilane

    Carbosilanes are compounds in which the elements of silicon and carbon alternate in a molecular framework or polymeric backbone in an approximate ratio of 1:1. By appropriate selection of the carbosilane precursor and deposition conditions the silicon carbide framework can be shifted toward substituted silicon and diamond-like structures.
