FIG. 1.

Schematic diagram of the unit bilayer structures with the Al–Zr layer in (a) a crystalline state; (b) an amorphous state; (c) the bulk Gibbs energy versus the composition of Co of the bilayer in (a) and (b) for the case that (Al, Zr)-cryst is more stable than (Al, Zr)-am. refers to the length and height, respectively.

Image of FIG. 2.
FIG. 2.

The Gibbs energy difference between the fcc (Al, Zr) solution and the amorphous (Al, Zr) phases versus the composition of Zr. Co-sputter-deposited alloys were made at composition points labeled (a)–(h).

Image of FIG. 3.
FIG. 3.

TEM micrographs and SAD patterns of Co-sputter-deposited Al–Zr alloy films with compositions of (a) , (b) , (c) , (d) , (e) , (f) , (g) , and (h) Zr.

Image of FIG. 4.
FIG. 4.

The XRD results of three typical films on glass: pure Zr , and pure Al .
