用固相烧结法合成了管状Sb2Se3相变材料,并通过扫描电子显微镜(SEM),X射线衍射仪(XRD),透射电镜(TEM)和拉曼光谱仪(Raman)对Sb2Se3晶体结构性能进行了表征测试,结果表明成功制备出正交晶系Sb2Se3。计算所得晶格常数为a(11.6445),b(11.792),c(3.981);透射电镜结果表明Sb2Se3微米管晶体结构沿[001]方向择优生长;同时用固相烧结法制备了不同配比的Sb-Se材料,并用XRD表征了晶体结构。
The Sb2Se3 phase-change material was synthesized by solid-state sintering. The properties of Sb2Se3 crystal were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM) and Raman spectroscopy The results show that the orthorhombic Sb2Se3 is successfully prepared. The calculated lattice constants were a (11.6445), b (11.792) and c (3.981), respectively. The transmission electron microscopy results showed that the crystal structure of Sb2Se3microelectrode grew preferentially along the [001] direction. Meanwhile, Sb-Se material and characterized by XRD.
