Figure 4From: Structural and photoluminescence studies on catalytic growth of silicon/zinc oxide heterostructure nanowiresHRTEM analysis on the Si/ZnO heterostructure NWs. TEM and HRTEM micrographs of Si/ZnO core-shell NWs prepared at different ZnO growth time of (a, b) 0.5, (c, d) 1, and (e, f) 1.5 h. Magnified HRTEM micrographs from (b) and (d) are inserted in the respective figures. FFT patterns inserted in (d) and (f) are converted from the appropriate HRTEM micrographs.Back to article page
