Abstract
Zinc oxide (ZnO) crystals were grown by the hydrothermal method under significantly improved conditions. Careful adjustment of critical growth conditions led the way towards ZnO crystals with extremely low (<1014 cm−3) lithium and potassium content. Photoluminescence reveals the low defect levels. The as-grown (0 0 0 1) surface exposes steps of 0.52 nm in height. High growth rates above 0.4 mm per day while observing narrow values for the X-ray rocking curve, FWHM from (0 0 2) reflection below 20 arcsec, and the growth of highly transparent, apparently colorless ZnO crystals are reported. Cautious co-doping with indium and lithium yields high-quality crystals.
