分别利用高密度电流和高温加热作为驱动力,在不同试样中产生原子迁移现象,并进行对比试验研究制备铝纳米线阵列的可行性。试验结果表明,在局部区域利用高密度电流成功制备了铝纳米线阵列。由于试样制备过程中蚀刻工艺带来的误差,导致电流密度相应变化,使试样在部分区域出现了爆破现象。高温加热的试样表面产生了大量铝纳米颗粒,但是由于原子迁移强度过低,未能在对应试样中制备出铝纳米线阵列。
The high-density current and high-temperature heating were used as the driving force respectively to generate atom migration phenomena in different samples. The comparative experiments were also conducted to study the feasibility of preparing aluminum nanowire arrays. The experimental results show that the array of aluminum nanowires has been successfully prepared by using high-density current in the local area. Due to the error caused by the etching process in the sample preparation process, the current density changes accordingly, causing the sample to explode in some areas. A large amount of aluminum nanoparticles were produced on the surface of the sample heated at high temperature, but the array of aluminum nanowires failed to be prepared in the corresponding sample due to too low atomic migration.
