Abstract
AbstractWe report here on selected optical properties of core/shell Zn1−xMnxTe/ZnO nanowires (NWs). The Zn1−xMnxTe cores of the investigated structures (containing from 3.5 to 7% of Mn) were grown by the MBE technique using gold‐catalyzed vapor–liquid–solid mechanism. Polycrystalline ZnO shells coating Zn1−xMnxTe NWs were overgrown by the atomic layer deposition (ALD) method. Core/shell NWs were then examined by scanning electron microscopy (SEM), X‐ray diffraction (XRD), Raman scattering, and photoluminescence (PL) measurements. The lines characteristic of the ZnO band edge emission and the intra‐Mn2+ transition were observed in the PL spectra. Modification of the Raman spectra of as‐grown Zn1−xMnxTe samples induced by the ZnO shell is demonstrated and discussed.
