( a ) Cross-sectional overview SEM image of the dual-polarity core-shell n-InGaN/p-Cu 2 O PD structure with the SEM image of the as-grown InGaN NWs in the inset. ( b ) ω−2θ XRD spectra of the bare core-shell InGaN NWs and the InGaN NW/Cu 2 O heterostructure on Si (111). ( c ) PL spectrum taken at room temperature of the core-shell InGaN NWs. ( d ) TEM image of a single core-shell InGaN NW with the corresponding HAADF image in the inset. ( e ) High-resolution TEM image of the InGaN NW core with the electron diffraction image in the inset. ( f ) Overlaid In and Ga EDX elemental mappings. ( g ) In and Ga EDX intensity line scans as indicated in ( f ). ( h ) EDX spectra taken at the core and shell positions indicated in ( f ).

Article Snippet: The structural properties were assessed by SEM (ZEISS Gemini 500), XRD (BRUKER D8 ADVANCE) and TEM (JEM-2100 h 200 KV) with an attached spectrometer (Bruker Dual QUANTAX 200) for EDX analysis.
