NMR Detection of Oxygen Isotopes in Ti02 Single Crystal*
نویسندگان
چکیده
We studied the electric quadrupole interactions of Oxygen isotopes in a T i 0 2 single crystal. For l 3 0 and 1 9 0 nuclei, quadrupole coupling constants were measured by the /3-NMR technique, and for the 1 7 0 nucleus the FT-NMR technique was utilized. We synthesized a T i0 2 single crystal which was enriched in 1 7 0 up to 5 atom % to observe NMR signals without any perturbations from impurities. Using the known quadrupole moment of l 7 0 , EFGs at an O site in T i 0 2 and the quadrupole moments of 1 3 0 and l 9 0 were determined.

HETEROEPITAXIAL GROWTH OF TiO2, VO2, AND TiO2/VO2 MULTILAYERS BY MOCVD
Titanium and vanadium dioxide systems were selected to study the MOCVD process for the growth of oxide epitaxial films. Single-crystal Ti02 and V02 films in single and multilayered configurations have been successfully grown on sapphire (a-Al203) single-crystal substrates. Seven distinct epitaxial orientation relationships between the films and the substrates were observed. Discussion on these ...

Single crystals consisting various surface morphologies and epitaxial structures were applied to investigate the effect of other phase regions in the vicinity of a given tethered chains-covered area having a certain molecular weight of amorphous brushes. The designed experiments demonstrated that regardless of the type of surface morphology (patterned and especial mixed-brushes, homo and co...
