| 因此，在200~300℃下对单晶纳米线退火时，AgSbTe2会分解生成Ag2Te和Sb2Te3。但在100℃下退火，AgSbTe2纳米线的结晶度反而增加，这是因为，在过低温度下分解反应缓慢，而纳米线中AgSbTe2晶体的再结晶和长大速度较快。随着温度增加，分解速度会大于再结晶速度。通过以上分析可知，在100℃附近对电沉积获得的AgSbTe2单晶纳米线进行热退火，可以提高纳米线结晶质量。 |

| So, annealing of the singel crystal nanowire at 200~300℃ will result in the decomposition of the AgSbTe2 into Ag2Te and Sb2Te3. But annealing at 100℃ will increase the crystallinity of AgSbTe2 nanowire. This is becuase, the decompostion rate is slow at low temperature, but the recrystallization and growth rates of the AgSbTe2 crystals in nanowire are much fasfter. With the increase of the temperature, the decomposition rate will become higher than the recrystallization rate. The above analysis results demonstrate that annealing the AgSbTe2 single crystal nanowire accquired by electrodeposition at a temperature around 100 C can increase the crystallinity of a nanowire. |

| Therefore, when annealing single-crystal nanoiwires under 200~300℃,the AgSbTe2 will be decomposed into Ag2T and Sb2Te3, but when annealing temperiture is under 100℃, the crystallinity of AgSbTe2 nanowires increased instead. The reason of this phenomenon is that the decomposition reaction of AgSbTe2 is much slower than the recrystallization and growth of AgSbTe2 nanowires. And with the tempertature increased, decomposition will be the main reaction. In conclution, around the temperature of 100℃,the quality of nanowires crystallization will be better, which the annealing of AgSbTe2 single-crystal nanoiwires is gained by electrodeposition. |
