✦ Synopsis

Vapour-deposited overgrowths of Na-6"-Al,O, that grow on p"-Al,O, single-crystal films at 1300-1350°C have been studied by X-ray diffraction and election microscopy. Overgrowth relationships are interpreted by matching the oxygen arrays of the deposited and background crystal lattice. Free energy calculations reveal the possible vapour-vapour reactions that lead to Na+"-Al,O, overgrowth formation.

Different morphologies of indium telluride (In 2 Te 3 ) including novel spherulites were crystallized using the physical vapour deposition (PVD) method, by varying the difference in the growth and source zone temperature (ΔT) of a dual zone horizontal furnace assembled indigenously. Whiskers and kin
