摘要
We investigated the conditions for the growth of Mn6+-doped from the ternary eutectic NaCl-KCl-CsCl solvent at temperatures of 480-600degreesC. The doping complex ion MnO42- can easily substitute the SO42- complex ion in BaSO4 with its orthorhombic space group Pnma. The growth of Mn6+-doped BaSO4 was performed using liquid-phase epitaxy by applying an advanced growth strategy. High-quality layers were grown according to the step-flow mode with step heights of maximum 1.5 unit cells and step widths of 200 run. The defect density was reduced to 1x10(3) and 7x10(4) etch pits cm(-2) for (011) and (001), respectively. The growth velocity was one and two unit cells s(-1) for <001> and <011>, respectively.
