报道了在羧基功能化多壁碳纳米管/聚酰亚胺(COOH-MWCNTs/PI)膜上电化学原子层沉积(EC-ALD)多壁碳纳米管/聚酰亚胺薄膜。用循环伏安法(CV)研究了其电化学性能，并用安培法(i-t)完成了ZnTe树枝晶的沉积。用X射线衍射仪(X射线衍射仪)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对所制备的树枝晶进行了表征。为了加深对晶体生长的理解，阐明了树枝晶的生长机制。试剂浓度和沉积周期对沉积产物的形貌和结构有显著影响。UV-Vis透射率研究表明其直接禁带宽度为2.26 eV。光电测量证实了树枝晶的p型导电性，表明树枝晶在光电子器件中具有潜在的实际应用价值。
We report on the electrochemical atomic layer deposition (EC-ALD) of ZnTe dendrites on the carboxyl-functionalized multi-walled carbon nanotubes/polyimide (COOH-MWCNTs/PI) membrane. Electrochemical characteristics were studied by cyclic voltammetry (CV) and the deposition of ZnTe dendrites was completed using amperometric method (I–t). The prepared ZnTe dendrites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The growth mechanism of ZnTe dendrites was elucidated to give a deep understanding of crystal growth. The concentration of reagents and deposition cycle had a significant effect on the morphology and structure of deposits. UV–vis transmission study indicated a direct band gap of 2.26eV. Photoelectrical measurement confirmed the p-type conductivity of ZnTe dendrites, which indicated that the dendritic ZnTe crystals may have potential practical application in optoelectronic devices.
