Zusammenfassung: | Embodiments of a layered-substrate comprising a substrate and a layer disposed thereon, wherein the layered-substrate is able to withstand fracture when assembled with a device that is dropped from a height of at least 100 cm onto a drop surface, are disclosed. The layered-substrate may exhibit a hardness of at least about 10 GPa or at least about 20 GPa. The substrate may include an amorphous substrate or a crystalline substrate. Examples of amorphous substrates include glass, which is optionally chemically strengthened. Examples of crystalline substrates include single crystal substrates (e.g. sapphire) and glass ceramics. Articles and/or devices including such layered-substrate and methods for making such devices are also disclosed. |
