To determine the CRYSTAL GROWTH orientation of the as-grown O4 single crystal, the wafers WERE cut IN A DIRECTION perpendicular to the CRYSTAL growth direction FOR XRD2 DETECTION. There is only one PEAK in the XRD2 image. Fig. 4 gives the XRD2 SPECTRA EXTRACTED from the XRD2 image. The peak at 42.7° REPRESENTS (400) plane.THE RESULT INDICATES that the O4 single crystals growED along the a-axis. According to the phase diagram of 2 system, nostoichiometric REACTION USUALLY result in A mixture of Zn2TiO4 and ZnO or ZnTiO3. IN ADDITION, no Z1 or Z2 WERE DETERMINED BY XRD and Raman. THEREFORE, IT IS SAFE TO CONCLUDE THAT the as-grown crystalS HAD A homogeneous STRUCTURE.
