采用差示扫描量热法研究了嵌入不同直径多孔阳极氧化铝膜孔中的锌纳米线的熔化行为。用X射线衍射和透射电子显微镜对Zn纳米线阵列的晶体结构和形貌进行了表征。Zn纳米线阵列的熔化温度与纳米线尺寸有很强的依赖性。熔化温度与纳米线直径的倒数随直径的变化呈曲线关系，并讨论了熔化热随尺寸的变化。(c)2006年，美国物理学会。
The melting behavior of Zn nanowires embedded in the holes of porous anodic alumina membrane with different diameters was studied by using the differential scanning calorimetry. The crystalline structure and morphology of Zn nanowire arrays were characterized by x-ray diffraction and transmission electron microscopy. The melting temperature of Zn nanowire arrays shows the strong dependence on nanowire sizes. The melting temperature was curvilinear with the reciprocal of the diameter of nanowires with the change of the diameter, which was discussed in terms of size-dependent heat of fusion change.
