Patent ID: 7211340

Claim:
A multiple layer structure comprising in overlying, contacting sequence: a first crystalline layer comprising a first fcc material having a <111> preferred growth orientation and a first {111} lattice parameter; a second crystalline layer comprising a second fcc material having a <111> preferred growth orientation and a second {111} lattice parameter different from said first {111} lattice parameter; and a third crystalline layer comprises an hcp material having a <0002> preferred growth orientation and a {0002} lattice parameter more closely matched to said second {111} lattice parameter than to said first {111} lattice parameter, wherein: said first fcc material is selected from the group consisting of: Ag, Au, Pt, Pd, Al, Rh, Ir, Pb, Ca, Sr, Yb, and alloys based thereon; said second fcc material is selected from the group consisting of: Ag, Cu, Au, Ni, Pt, Pd, Al, Rh, Ir, Pb, Ca, Sr, Yb, and alloys based thereon; and said hcp material is selected from the group consisting of: Ru, Ti, Co, Re, Be, Mg, Sc, Zn, Se, Zr, Cd, Te, La, Hf, Os, Ti, Pr, Nd, Gd, Tb, Dy, Ho, Er, Tm, Lu, Y, and alloys based thereon.
