Abstract:
A method for fabricating a semiconductor structure capable of controlling antiphase domains in the semiconductor structure, the method comprising:providing a monocrystalline silicon substrate; depositing a monocrystalline perovskite oxide film overlying the monocrystalline silicon substrate, the film having a thickness less than a thickness of the material that would result in strain-induced defects; forming an amorphous oxide interface layer containing at least silicon and oxygen at an interface between the monocrystalline perovskite oxide film and the monocrystalline silicon substrate; epitaxially forming a monocrystalline compound semiconductor layer overlying the monocrystalline perovskite oxide film; and suppressing the formation of anti-phase domains during fabrication of the semiconductor structure.
