Sketch of an a-ZnO epitaxial layer on r-sapphire. (a) Mutual orientation of crystallographic cells of an a-ZnO heteroepitaxial layer on r-sapphire substrate. (b) Coincidence-site lattices of an interface ZnO(110) epitaxial layer on Al2O3([1\overline{1}2]) with anchors A1{ZnO[003]; Al2O3[[\overline{1} 1 1]]}, A2{ZnO[[\overline{1}10]]; Al2O3[110]} of a-ZnO on r-sapphire.  [article HTML]
