Growth of Thick Zinc Magnesium Oxide by Liquid Phase Epitaxy

Very thick (about 0.5 mm) single crystals of a (Zn,Mg)O were grown on ZnO substrate by using a liquid phase epitaxy (LPE) technique. The source materials, ZnO and MgO, were dissolved in a PbO–Bi2O3 flux, and the (Zn,Mg)O was crystallized on the c-face of ZnO substrate in contact with the melt. The obtained crystal had high crystallinity similar to that of the ZnO substrate and exhibited n-type conductivity with relatively high Hall mobility.
