摘要：

One dimensional zinc oxide nanostructures have great potential for applications in the fields of optoelectronic and sensor devices. In this paper, we present the synthesis of ZnO/ZnMgO heterostructures on c- plane Al2O3 by plasma-assisted molecular beam epitaxy and investigation of their structural and optical properties. We demonstrate that it is possible to grow a good quality nanocolumns on c- plane Al2O3 substrate without employing a catalyst such as Au or Ag. We have also studied a shift between polar- and nonpolar- ZnO/ZnMgO quantum wells. The non-polar a- plane ZnO/ZnMgO nanocolumns were achieved on r- plane sapphire substrate, while the on polar c-plane substrate was used to obtain a polar c-orientation of the nanostructures.
