Growth conditions and structural properties of ZnMgO nanocolumns on Si(111)

The ZnMgO nanocolumns were obtained at different growth conditions. Scanning electron microscopy (SEM) images show that diameters and density of ZnMgO nanorods on Si(111) surface can be controlled by the growth temperature of nanocolumns and temperature of the buffer structures grown. The crystalline quality of the heterostructure was characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Optical properties of the ZnMgO structure were studied by photoluminescence (PL) spectroscopy.
