【摘要】 用自制的设备制备了取向和无取向氧化铟纳米线,并研究了In2O3纳米线的场发射性质,发现取向纳米线比非取向纳米线有着更好的场发射特性.取向纳米线的开启和阈值场强明显低于非取向纳米线,这可能是由于取向纳米线之间的场屏蔽效应较弱以及取向纳米线有较多的顶部发射端的缘故.更多还原

【Abstract】 Aligned and unaligned In-2O-3 nanowires were prepared based on our homemade equipment and the field-emission properties of In-2O-3 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.更多还原
