Aligned and unaligned In2O3 nanowires were prepared based on our homemade equipment and the field-emission properties of In2O3 nanowires(NWs) were investigated.It was found that aligned In2O3 NWs have better performance than unaligned ones. The aligned NWs have lower turn-on and threshold electric fields. This might be attributed to the weaker field-screening effect between the neighboring aligned NWs, and the existence of more exposed tips as emitters in the aligned NWs.
