Abstract:
A substrate comprising:a base substrate; an interfacial bonding layer disposed on the base substrate; and a thin film adaptive crystalline layer disposed on the interfacial bonding layer, wherein: the interfacial bonding layer is solid at approximately 100Â° C. and acquires a liquid-like form at a bonding layer melting point lower than the melting points of the base substrate and the thin film adaptive crystalline layer; the thin film adaptive crystalline layer has a degree of flexibility to expand or contract its lattice constant along a direction parallel to a surface of the substrate when the interfacial bonding layer is in liquid-like form; and the base substrate is mechanically strong enough to support the interfacial bonding layer and the thin film adaptive crystalline layer thereon.
