我们证明了三元Zn2GeO4晶体可以作为潜在的晶格匹配的ZnO纳米棒阵列生长的衬底。单晶Zn2GeO4纳米线被用作ZnO纳米棒阵列的晶体学取向的衬底。结构表征验证了ZnO c面和Zn2GeO4侧面之间的异质外延生长，这是由于小的晶格失配。半导体Zn2GeO4晶体作为ZnO纳米棒阵列生长的新型替代衬底具有潜在的兴趣。
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.
