Zinc oxide single crystals implanted at room temperature with high-dose (1.4 x 10{sup 17} cm{sup -2}) 300 keV As{sup +} ions are annealed at 1000-1200 C. Damage recovery is studied by a combination of Rutherford backscattering/ channeling spectrometry (RBS/C), cross-sectional transmission electron microscopy (XTEM), and atomic force microscopy (AFM). Results show that such a thermal treatment leads to the decomposition and evaporation of the heavily-damaged layer instead of apparent defect recovery and recrystallization that could be inferred from RBS/C and XTEM data alone. Such a relatively poor thermal stability of heavily-damaged ZnO has significant implications for understanding results on thermal annealing of ion-implanted ZnO.
