Abstract:
A process for fabricating a perovskite heterostructure comprising the steps of:providing a silicon substrate; epitaxially growing a first monocrystalline layer comprising (Ba,Sr)TiO3 overlying the silicon substrate; forming an amorphous layer of silicon oxide underlying the first monocrystalline oxide layer during the step of epitaxially growing the first monocrystalline oxide layer; epitaxially growing a second monocrystalline layer comprising (La,Sr)CoO3 overlying the first monocrystalline oxide layer; epitaxially growing a third monocrystalline layer comprising Pb(Zr,Ti)O3 overlying the second monocrystalline layer; and epitaxially growing a fourth monocrystalline layer comprising (La,Sr)CoO3 overlying the third monocrystalline layer.
