A novel strain mismatch induced tilted epitaxy method has been demonstrated for producing high quality (000l) hexagonal films on (001) cubic substrates. Highly oriented hexagonal (000l) ZnO films are grown on (001) MgO using Sm0.28Zr0.72O2−δ as a template. The work opens up a new avenue for growing technologically important hexagonal structures on readily available cubic substrates and gives wide possibilities for heteroepitaxial growth of a range of dissimilar materials.
