    摘要:

    在真空管式爐內(nèi),以Bi2Te3為蒸發(fā)源,在蒸發(fā)溫度560 ℃,保溫時(shí)間2h條件下,采用熱蒸發(fā)法在涂有Au溶膠的石英基片上制備出了大量碲納米線。通過XRD、SEM、HRTEM等儀器對(duì)碲納米線的組織結(jié)構(gòu)和微觀形貌進(jìn)行了表征與分析。結(jié)果表明,制備出的碲納米線為沿(101)方向取向生長(zhǎng)的三方單晶碲納米線,直徑范圍在40~100nm之間,生長(zhǎng)機(jī)制符合VLS生長(zhǎng)機(jī)制。蒸發(fā)源材料和Au溶膠是熱蒸發(fā)法制備碲納米線的關(guān)鍵因素。

    Abstract:

    A large number of tellurium nanowires were prepared on quartz substrates coated with Au sol by thermal evaporation method in a vacuum tube furnace with Bi2Te3 as the source at 560 °C for 2h. The microstructure and morphology of tellurium nanowires were characterized by XRD, SEM and HRTEM. The results showed that the as prepared tellurium nanowires were cubic single crystal tellurium nanowires oriented along the (101) direction with diameters ranging from 40 to 100 nm. The growth mechanism conforms to the VLS growth mechanism .The evaporation source material and Au sol were the key factors for the preparation of tellurium nanowires by thermal evaporation.
