Ck. Kuo et Ps. Nicholson, MICROSCOPIC STUDY OF THE BETA''-AL2O3 SINGLE-CRYSTAL-FILM GROWTH-MECHANISM ON SAPPHIRE SUBSTRATES, Solid state ionics, 82(3-4), 1995, pp. 173-178
The microstructure of beta ''-Al2O3 single-crystal films grown on sapp
hire substrates has been studied. A film-growth mechanism based on bet
a ''-Al2O3 formation and crystal incorporation is suggested.
