Abstract: Zinc oxide (ZnO) bulk single crystals, which are of high purity and transparency with a large size of 2 in., are successfully grown by the hydrothermal method. The sliced substrates are chemomechanically polished to form an epi-ready surface. The impurities existing on the as-polished substrate surface are characterized before and after annealing by SIMS (secondary-ion mass spectroscopy), and a damaged surface layer due to chemomechanical polishing is evaluated by an optical method. We attempt to remove the l…
