Abstract:
A pyroelectric detector circuit comprising:a monocrystalline silicon substrate; a portion of a MOS circuit formed in the monocrystalline silicon substrate; a first monocrystalline perovskite layer formed of material selected from the group comprising BaTiO3, SrTiO3, and CaTiO3 and epitaxially grown overlying the silicon substrate; a second monocrystalline perovskite layer formed of material selected from the group comprising (La, Sr)CoO3, SrRuO3, SrVO3, BaRuO3, BaVO3 and (La, Ca)MnO3 overlying the first monocrystalline pyroelectric layer; a monocrystalline pyroelectric layer formed of perovskite material from the group comprising Pb(Ti, Zr)O3, PbTiO3, BaTiO3, Pb(Sc, Ta)O3, Bi(Ti, Zr)3O12, SrBi2(Ta, Nb)2O9 and YMnO3; and an electrical connection electrically coupling the portion of a MOS circuit and the second monocrystalline perovskite layer.
