K. Brohl et al., EPITAXIAL-GROWTH OF CO FILMS AND CO CU SUPERLATTICES ON SAPPHIRE SUBSTRATES WITH AND WITHOUT BUFFER LAYERS/, Journal of crystal growth, 127(1-4), 1993, pp. 682-685
Co(0001)/(111) films and Co/Cu(111) multilayers were grown by MBE on s
apphire (1120BAR) substrates. Co grows in a good epitaxial manner dire
ctly on the sapphire substrate as well as on a Cu(111)/Nb(110) buffer
layer system. Co/Cu(111) superlattices were grown on the same buffer s
ystem. Extensive RHEED and X-ray characterizations demonstrate the hig
h film quality.
