概要

論文の詳細を見る
We report on the fabrication of Ge nanosheets decorated ZnSe/GeSe hierarchical heterostructure nanowires via a simple one-step thermal evaporation of ZnSe and Ge powder. A typical Ge nanosheets decorated ZnSe/GeSe hierarchical heterostructure nanowire consists of ZnSe/GeSe bi-coaxial nanowire, secondary nanostructures of GeSe nanobrushes are grown on the primary ZnSe/GeSe bi-coaxial nanowire, Ge nanosheets are decorated on the GeSe nanobrushes. The possible growth mechanism of the novel hierarchical nanowire heterostructures is discussed. In addition, the vibrating properties of Ge decorated ZnSe/GeSe hierarchical heterostructure nanowires are studied by using Raman spectroscopy.
