摘要:
A high quality epitaxial layer of monocrystalline Pb(Zr,Ti)O3 can be grown overlying large silicon wafers by first growing an strontium titanate layer on a silicon wafer. The strontium titanate layer is a monocrystalline layer spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide.
