Abstract

We demonstrated that ternary Zn₂GeO₄ crystals could be used as potential lattice-matched substrates for ZnO nanorod array growth. Single-crystalline Zn₂GeO₄ nanowires were used as substrates for crystallographic alignment of ZnO nanorod arrays. Structural characterization verified the heteroepitaxial growth between the ZnO c-plane and Zn₂GeO₄ side facets, which was attributed to the small lattice mismatches. The semiconducting Zn₂GeO₄ crystals are of potential interest as novel alternative substrates for ZnO nanorod array growth.
