摘要: 硝酸溶液中运用脉冲电化学方法，在ITO导电玻璃表面成功制备了热电Bi2Se0.3Te2.7/Te异质结构多层纳米线阵列材料。运用XRD对制备的样品物相进行表征，通过FE-SEM和TEM对样品的表面形貌进行观察。研究结果表明，所制备的材料是热电Bi2Se0.3Te2.7/Te异质结构纳米线阵列；多层纳米线直径为大约200~250 nm。从高倍透射电镜照片可以看出，多层纳米线具有周期性的结构，并且可以清晰地辨认出Bi2Se0.3Te2.7和Te两相的分界面。选区电子衍射(SAED)结果进一步证实了所制备的样品非单一相，体现了异质结构材料的本质。研究结果为制备其它多层异质结构纳米线阵列材料指明了方向。
Abstract: Thermoelectric Bi2Se0.3Te2.7/Te heterostructure nanowire arrays were fabricated on ITO-coated glass substrate by pulsed electrochemical method from nitric acid solution. The phase of the as- prepared sample was determined by XRD. In addition, the surface morphology of the as-fabricated nanowires was analyzed by FE-SEM and TEM. The results showed that the as-prepared materials were thermoelectric Bi2Se0.3Te2.7/Te heterostructure nanowire arrays with the diameter of about 200~250 nm. Besides, multi-layered nanowires with periodical structure could be seen from magnified TEM picture. Meanwhile, the interface between Bi2Se0.3Te2.7 and Te could be distinguished clearly. Moreover, the result of SAED also confirmed the as-fabricated sample was not single phase. This displayed the nature of the heterostructure material. Finally, our work pointed out the direction for prepared other heterostructure nanowire arrays materials.
