Figure 4

TEM:a BFI of tapered W-ZnO whiskers;b Magnified BFI of an individual twinned whisker with SAED patterns;c andd taken from root and middle areas, respectively, showing the twin domains are slightly off as indicated by spot splitting (circled) inc, but are in exact zone axis ind, having twin spot denoted as t and double diffraction denoted asd;e andf Magnified BFIs from specified areas showing facets and a curved growth ledge;g The Lattice image and the 2-D forward Fourier transform from the square region showing that the whisker tip is a single crystal with facets as in the case ofe and (f). Note: a nearby ledge (arrowed) orthogonal to the side surface ; The same specimen as in Fig. 3b
