Abstract

Highly aligned one-dimensional (1D) nanorods of the transparent conducting oxide In(2)O(3) have been grown on (110)-oriented Y-stabilized ZrO(2) substrates, whereas growth on (100) and (111) substrates leads respectively to blocklike 3D islands and continuous films. It is shown that the striking influence of substrate orientation on the growth morphology is controlled by differences in energies between the low index surfaces of In(2)O(3) and that spontaneous self-organization is driven by minimization of surface energies.

摘要

高度排列的一维（1D）氧化铟（In2O3）纳米棒已在（110）取向的 Y 稳定氧化锆（ZrO2）衬底上生长，而在（100）和（111）衬底上则分别生长出块状的 3D 岛和连续膜。研究表明，衬底取向对生长形态的显著影响是由 In2O3低指数表面之间的能量差异控制的，而自发的自组织则是由表面能的最小化驱动的。
