Abstract

We investigated the growth mechanism of ZnO(001) nanorods on SrTiO₃(001) substrates. In the beginning of ZnO growth, a ZnO(110) film was developed on SrTiO3 substrates and then (001)- oriented ZnO nanorods grew on the ZnO(110) film. The strain energy of ZnO(110) growth on SrTiO₃ (001) planes was approximately 2.7 × 10⁸ J/m³ whereas it was estimated to be ∼1.61× 10 9 J/m³ for ZnO(001) directly grown on SrTiO₃ (001) planes using Young's modulus of elasticity. Stress due to the lattice mismatch between ZnO and SrTiO₃ was mostly relaxed in several monolayers and then ZnO(001) nanorods were finally formed along their easy growth directions.
