Figure 3From: Improvement of the physical properties of ZnO/CdTe core-shell nanowire arrays by CdCl2 heat treatment for solar cellsHRTEM image and Fourier-filtered enhancement. (a) HRTEM image of an as-grown ZnO/CdTe core-shell NW. The insets are Fourier-filtered enhancements along the [100] and [1-10] zone axes of the ZnO NW and CdTe NG, respectively. (b) Fourier-filtered enhancement collected at the ZnO/CdTe interface, as depicted in the blue rectangular area in (a).Back to article page
