ZnTe-ZnO core-shell radial heterostructures were grown using a new method of combining molecular beam epitaxy (MBE) and atomic layer deposition (ALD). Zinc telluride nanowires (core) were grown on a GaAs substrate using gold catalyzed vapor-liquid-solid mechanism. An atomic layer deposition technique using diethyl zinc and deionized water as precursors was applied for zinc oxide shell formation. The core-shell ZnTe-ZnO heterostructures thus obtained were characterized by scanning electron microscopy, transmission electron microscopy, x-ray diffraction and photoluminescence measurements.
采用分子束外延（MBE）和原子层沉积（ALD）相结合的新方法生长了 ZnTe-ZnO 核壳径向异质结构。使用金催化的气-液-固机制在 GaAs 衬底上生长了碲化锌纳米线（核）。使用二乙基锌和去离子水作为前驱体的原子层沉积技术用于形成氧化锌壳。通过扫描电子显微镜、透射电子显微镜、X 射线衍射和光致发光测量对所得到的核壳 ZnTe-ZnO 异质结构进行了表征。
