Is diamond amorphous or crystalline
WebHowever, these previous high pressure studies are all based on crystalline carbon phases. Under certain circumstances non-crystalline materials can be advantageous than crystalline forms. Extensive efforts in making diamond-like amorphous carbon [16-18] and tetrahedral amorphous carbon [19-24] using subplantation of incident ions have produced thin WebFigure 1. The entities of a solid phase may be arranged in a regular, repeating pattern (crystalline solids) or randomly (amorphous). Metals and ionic compounds typically form ordered, crystalline solids. Substances that consist of large molecules, or a mixture of molecules whose movements are more restricted, often form amorphous solids.
