Figure 2From: Single nanowire-based UV photodetectors for fast switching Structural characterization of the ZnO nanowires. (a) HRTEM image of the edge of an as-synthesized ZnO nanowire. The spacing of 0.26 nm between adjacent lattice planes corresponds to (002) lattice planes of ZnO and <0001> growth direction is also shown; (b) XRD spectrum of the ZnO nanowires.Back to article page
